Acids and Bases: The Theories answer key

To distinguish the contents of each test tube, some simple tests can be performed:

For the calcium chloride solution: a small amount of silver nitrate solution can be added to the test tube. If a white precipitate forms, this indicates the presence of chloride in the solution.

For calcium carbonate suspension: A few drops of dilute hydrochloric acid can be added to the test tube. If an effervescence occurs, this indicates the presence of carbonate in the suspension.

For the milk colloid: the appearance of the contents of the test tube can be observed. If the content appears cloudy and opaque, this indicates the presence of a colloid. Also, if a pH indicator such as phenolphthalein is added, the solution will remain pink, indicating that there is not a significant amount of acid or base present in the solution.

The concentration of Ag+ in the cathode solution is 3.02 M.

To determine the concentration of ions in the cathode solution, we need to use the Nernst equation, which relates the cell potential to the standard cell potential and the concentrations of the ions in the anode and cathode solutions:

Anode: Cu2+/Cu

Cathode: Ag+/Ag

Temperature: 328 K

Non-standard cell potential: 0.414 V

Ecell = E°cell - (RT/nF) ln Q

where,

Ecell = non-standard cell potential

E°cell = standard cell potential

R = gas constant

T = temperature in Kelvin

n = number of electrons transferred in the balanced equation

F = Faraday's constant

Q = reaction quotient, which is the ratio of the concentrations of the products to the concentrations of the reactants

We can start by writing the balanced equation for the cell reaction:

Cu(s) + 2Ag+(aq) → Cu2+(aq) + 2Ag(s)

From the equation, we can see that 2 electrons are transferred in the reaction. So, n = 2.

The standard reduction potential for Ag+/Ag is +0.80 V, and for Cu2+/Cu, it is +0.34 V. Therefore, the standard cell potential, E°cell, can be calculated as:

E°cell = E°cathode - E°anode

E°cell = +0.80 V - (+0.34 V)

E°cell = +0.46 V

Now, we can use the Nernst equation to find the concentration of Ag+ in the cathode solution, given that the concentration of Cu2+ in the anode solution is 0.100 M:

Ecell = E°cell - (RT/nF) ln Q

0.414 V = +0.46 V - (0.0257 V/K) (ln Q/2)

where,

R = 8.314 J/K·mol

F = 96,485 C/mol

ln = natural logarithm

Solving for Q:

ln Q = (2 × (0.46 V - 0.414 V) × 96,485 C/mol) / (0.0257 J/K·mol × 2)

ln Q = 4.51

Q = e^(4.51)

Q = 91.4

Since Q = [Ag+]^2 / [Cu2+], and [Cu2+] = 0.100 M, we can solve for [Ag+]:

91.4 = [Ag+]^2 / 0.100

[Ag+]^2 = 9.14

[Ag+] = 3.02 M

The partial pressure of [tex]O_2[/tex] is -146 mmHg

The given problem involves a gas mixture consisting of [tex]N_2, CO_2[/tex], and [tex]O_2[/tex] at a total pressure of 730 mmHg. The partial pressure of [tex]CO_2[/tex] is given as 182 mmHg, and it is also given that there are twice as many moles of [tex]N_2[/tex] as there are of [tex]CO_2[/tex].

To solve the problem, we need to use Dalton's law of partial pressures, which states that the total pressure of a mixture of gases is equal to the sum of the individual gases. We can also use the mole fraction concept, which is the ratio of the number of moles of a gas to the total number of moles of all gases in the mixture.

Let x be the number of moles of [tex]CO_2[/tex] in the mixture.

Then, the number of moles of [tex]N_2[/tex] is 2x. Therefore, the number of moles of [tex]O_2[/tex] is (total number of moles) - (number of moles of [tex]CO_2[/tex]) - (number of moles of [tex]N_2[/tex]), which is x/2.

We can now use the mole fraction concept to calculate the mole fractions of each gas. The mole fraction of

[tex]CO_2[/tex] is

x/(2x + x + x/2) = 2x/5x = 0.4.

Similarly, the mole fraction of

[tex]N_2[/tex] is 2x/(2x + x + x/2) = 4x/5x = 0.8.

The mole fraction of

[tex]O_2[/tex] is (x/2)/(2x + x + x/2) = x/5x = 0.2.

Finally, we can use Dalton's law of partial pressures to calculate the partial pressure of oxygen:

Total pressure = P([tex]N_2[/tex]) + P([tex]CO_2[/tex]) + P([tex]O_2[/tex])

730 mmHg = P([tex]N_2[/tex]) + 182 mmHg + P([tex]O_2[/tex])

Substituting the mole fraction and pressure values, we get:

730 mmHg = (0.8)(730 mmHg) + (0.4)(730 mmHg) + P([tex]O_2[/tex])

730 mmHg = 584 mmHg + 292 mmHg + P([tex]O_2[/tex])

P([tex]O_2[/tex]) = 730 mmHg - 876 mmHg

P([tex]O_2[/tex]) = -146 mmHg

percent yield: 65.3%.

Given chemicals: NaOH, H₂SO₄. Wanted chemical: Na₂SO₄.

The theoretical yield is therefore 497.14 g of Na₂SO₄.

Mole ratio: 2 moles NaOH : 1 mole H₂SO₄ : 1 mole Na₂SO₄.

Molar mass: Na₂SO₄, with a molar mass of 142.04 g/mol.

Theoretical yield:

From the balanced equation, 2 moles of NaOH react with 1 mole of H₂SO₄ to produce 1 mole of Na₂SO₄.

So, 5.00 moles of NaOH will react with (7.00 moles H₂SO₄ / 2.00 moles NaOH) = 3.50 moles of H₂SO₄.

From the mole ratio, the number of moles of Na₂SO₄ produced will be the same as the number of moles of H₂SO₄ used.

Therefore, the number of moles of Na₂SO₄ produced will be 3.50 moles.

The mass of Na₂SO₄ produced can be calculated by multiplying the number of moles by the molar mass: 3.50 mol × 142.04 g/mol = 497.14 g.

The theoretical yield is therefore 497.14 g of Na₂SO₄.

Percent yield:

Given: actual yield = 325 g of Na₂SO₄.

Using the first law of thermodynamics, we know that q (heat) + w (work) = ΔE (change in internal energy). Since we are given the work done on the system (w = 357 J) and the change in internal energy (ΔE = 958 J), we can solve for q for the system is 601 J.

According to the first law of thermodynamics, the energy of a system can be conserved, but it can be transformed from one form to another. The equation for the first law of thermodynamics is:

ΔE = q + w

Where ΔE is the change in internal energy, q is the heat transferred into or out of the system, and w is the work done on or by the system.

In this case, we know that the internal energy changes by 958 J, and 357 J of work is done on the system. To find q, we can rearrange the first law equation:

q = ΔE - w

q = 958 J - 357 J

q = 601 J

The pH of the buffer after the addition of 0.03 mol of KOH is 5.04.

To answer this question, we need to use the Henderson-Hasselbalch equation, which relates the pH of a buffer solution to the concentration of the acid and its conjugate base:

pH = pKa + log([A-]/[HA])

where pKa is the dissociation constant of the acid, [A-] is the concentration of the conjugate base (in this case, sodium acetate), and [HA] is the concentration of the acid (acetic acid).

First, we need to calculate the initial concentrations of acetic acid and sodium acetate:

[HA] = 0.10 mol/L
[A-] = 0.14 mol/L

Next, we need to calculate the new concentrations of acetic acid and sodium acetate after the addition of 0.03 mol of KOH. Since KOH is a strong base, it will react completely with the acetic acid to form acetate ion:

CH3COOH + KOH -> CH3COO- + H2O

The amount of acetic acid that reacts with KOH is:

0.03 mol KOH / 1 L = 0.03 M

Since acetic acid and KOH react in a 1:1 ratio, the concentration of acetic acid is now:

[HA] = 0.10 mol/L - 0.03 mol/L = 0.07 mol/L

The amount of acetate ion that is formed is also 0.03 mol/L, since acetic acid and acetate ion are in equilibrium:

CH3COOH <--> CH3COO- + H+

Since the buffer initially contained 0.14 mol/L of sodium acetate, the new concentration of acetate ion is:

[A-] = 0.14 mol/L + 0.03 mol/L = 0.17 mol/L

Now we can calculate the pH of the buffer using the Henderson-Hasselbalch equation:

pH = 4.76 + log(0.17/0.07) = 5.04

Explanation:

The balanced chemical equation for the reaction between aluminum (Al) and oxygen (O2) to form aluminum oxide (Al2O3) is:

4 Al + 3 O2 → 2 Al2O3

According to the problem, we know that the limiting reactant is O2 and that it forms 2.7 mol of Al2O3. We can use the stoichiometry of the balanced chemical equation to calculate the amount of Al2O3 that would be formed from 3 mol of O2, which is the amount that would react with 4 mol of Al:

4 Al + 3 O2 → 2 Al2O3

3 mol of O2 → 2 mol of Al2O3

We can use the mole ratio from the balanced equation to convert the amount of O2 that reacted to the amount of Al2O3 that formed:

2.7 mol of Al2O3 × (3 mol of O2 / 2 mol of Al2O3) = 4.05 mol of O2

This tells us that if we had 4.05 mol of O2, it would react completely with 4 mol of Al to form 2.7 mol of Al2O3. However, since we only have a limited amount of O2 (the limiting reactant), we know that not all of the Al will react, and some of it will be left over.

To calculate the mass of Al2O3 that forms, we can use the amount of O2 that reacted (which we just calculated) to determine the amount of Al that reacted:

4 Al + 3 O2 → 2 Al2O3

4.05 mol of O2 × (4 mol of Al / 3 mol of O2) = 5.4 mol of Al

This tells us that 5.4 mol of Al reacted with the 2.7 mol of Al2O3 that formed. To calculate the mass of Al2O3, we can use the mole ratio from the balanced equation and the molar mass of Al2O3:

2.7 mol of Al2O3 × (102 g/mol) = 275.4 g of Al2O3

Therefore, the mass of Al2O3 that forms is 275.4 g.

The metals that would act as sacrificial anodes for iron are: zinc (Zn), aluminum (Al), magnesium (Mg), and cadmium (Cd).

These metals have a higher tendency to undergo oxidation (lose electrons) than iron, so when they are connected to iron, they will corrode in preference to the iron, effectively protecting the iron from corrosion.

Despite its ability to act as a sacrificial anode for iron, sodium (Na) is not suitable to attach to the hull of a steel ship due to its high reactivity with water. Sodium reacts vigorously with water, producing hydrogen gas and high levels of heat, which could cause an explosion or fire on the ship.

When aqueous ammonia is added to the half-cell containing 0.001 M CuSO4, the cell potential is likely to change. The reason for this is that ammonia can form coordination complexes with copper ions, which can affect the concentration of copper ions in the solution, and hence the concentration gradient that drives the redox reaction in the cell.

Ammonia can react with copper ions in aqueous solution to form a series of coordination complexes. The most common complex is Cu(NH3)42+, which is a tetraamminecopper(II) complex. The formation of this complex reduces the concentration of free Cu2+ ions in solution, which can shift the equilibrium of the redox reaction in the cell.

If the reduction half-reaction is Cu2+ + 2e- → Cu, the addition of ammonia can reduce the concentration of Cu2+ ions in the solution and shift the equilibrium to the left, decreasing the cell potential. On the other hand, if the oxidation half-reaction is Cu → Cu2+ + 2e-, the addition of ammonia can increase the concentration of Cu2+ ions and shift the equilibrium to the right, increasing the cell potential.

The cross-linking of PVA and boric acid is sustained by a combination of covalent and non-covalent interactions, including hydrogen bonding and van der Waals forces. These interactions lead to the formation of a stable, three-dimensional network structure that has a range of potential applications, including in the development of new materials with unique properties.

Polyvinyl alcohol (PVA) can form cross-linked networks when reacted with boric acid. The cross-linking is due to the formation of borate ester linkages between PVA chains and boric acid molecules. The formation of these linkages is facilitated by a combination of covalent and non-covalent interactions, including hydrogen bonding and van der Waals forces.

Hydrogen bonding is a particularly important intermolecular force that plays a key role in the formation and stability of the cross-linked PVA network. PVA contains hydroxyl (-OH) groups along its polymer chains that can form strong hydrogen bonds with the borate groups on boric acid molecules. This interaction leads to the formation of a three-dimensional network structure that is stabilized by the formation of multiple hydrogen bonds between adjacent PVA chains and boric acid molecules.

Van der Waals forces also contribute to the stability of the cross-linked network. These forces arise from the fluctuating dipoles in atoms and molecules and are responsible for the attraction between non-polar species. In the PVA-boric acid system, van der Waals forces between the polymer chains and boric acid molecules help to stabilize the cross-linked network.

The no of grams of aluminum are required to react with 95ml of 3. 3m hydrochloric acid, HCI is 2.82 g .

To determine the grams of aluminum required to react with 95 mL of 3.3M hydrochloric acid (HCl), you need to use stoichiometry. The balanced chemical equation for the reaction is:

2 Al + 6 HCl → 2 Al[tex]Cl_{3}[/tex] + 3 H2

First, convert the volume of HCl to moles using the molarity:

moles HCl = (3.3 moles/L) × (95 mL × (1 L / 1000 mL)) = 0.3135 moles HCl

Next, use the stoichiometric ratio to find the moles of aluminum:

moles Al = (0.3135 moles HCl) × (2 moles Al / 6 moles HCl) = 0.1045 moles Al

Finally, convert moles of aluminum to grams using the molar mass of aluminum (26.98 g/mol):

grams Al = (0.1045 moles Al) × (26.98 g/mol) = 2.82 g

Therefore, 2.82 grams of aluminum are required to react with 95 mL of 3.3 M hydrochloric acid.

It is believed that the pharmacology book composed by Biruni shortly after AD 1000 contained the first written description of the process of distillation.

This technique involves heating a liquid mixture to vaporize certain compounds, which are then condensed back into a liquid form and collected separately.

Biruni's description of distillation is considered significant because it paved the way for the development of many important chemical processes, such as the production of essential oils, perfumes, and alcoholic beverages.

Additionally, distillation has played a key role in the development of modern chemistry and is still widely used today in a variety of industries, including pharmaceuticals, petroleum refining, and food and beverage production.
