Question 1

What is the correct mathematical expression for finding the molar solubility (s)of Sn(OH)₂?

Accepted Answer

B

Question 2

What is the solubility product expression for Pb(IO₃)₂?

Accepted Answer

The correct solubility product expression for Pb(IO3)2 is Ksp = [Pb^2+][IO3^-]^2. This is because the compound dissociates into one Pb^2+ ion and two IO3^- ions in solution.

Question 3

What is the solubility product expression for Zn₃(PO₄)₂?

Accepted Answer

The solubility product expression for ZnS is [Zn2+][S2-]. In the given compound, there are multiple instances of Zn and S ions, each denoted by a subscript. However, the subscripts are not necessary in the solubility product expression since the compound is insoluble and dissociates as a whole. So, we can write the expression as [ZnS] = [Zn2+][S2-]. From the given options, only option E correctly represents this expression by substituting the ions and removing the unnecessary subscripts.

Question 4

Figures I-IV represent ionic compounds formed upon the mixing of an aqueous solution containing cation C with an aqueous solution containing anion A.Identify the figure(s)that represent(s)products for which K_sp = 108s⁵,where s is the molar solubility of the ionic compound.

Accepted Answer

Only figure IV has a molar solubility of s = K_sp = 108s⁵, as requested in the question. None of the other figures have the same value of solubility.

Question 5

Cation C and anion A form an ionic compound for which K_sp = 4s³,where s is the molar solubility of the ionic compound.Which of Figures I-III represent(s)possible results of the mixing of an aqueous solution containing cation C with an aqueous solution containing anion A?

Accepted Answer

The given expression K_sp = 4s³ is the solubility product expression for the ionic compound formed by cation C and anion A. It is given that s is the molar solubility of the ionic compound. In order for the ionic compound to form in an aqueous solution, the concentrations of cation C and anion A must exceed the solubility product constant, K_sp, such that precipitation can occur. From the given expression, we can see that the product of the concentrations of cation C and anion A is directly proportional to the molar solubility of the ionic compound, s. Therefore, we can conclude that the concentration of cation C or anion A alone is not sufficient for precipitation to occur, but it is the product of their concentrations that matters. Looking at the figures, we can see that both I and II represent aqueous solutions containing either cation C or anion A alone, and hence, precipitation will not occur in these cases. Figure III, on the other hand, represents the mixing of aqueous solutions containing both cation C and anion A, which can result in precipitation if their concentrations exceed the solubility product constant, K_sp, as given in the solubility product expression. Therefore, the possible result of the mixing of aqueous solutions containing cation C and anion A is represented by Figure III, and hence, the correct answer is C.

Question 7

What is the solubility product expression for Al(OH)₃?

Accepted Answer

The solubility product expression for Al(OH)3 is [Al3+][OH-]^3. Since there are three hydroxide ions in the formula for Al(OH)3, the solubility product expression becomes [Al3+][OH-]^3. The 1+ charges on the Al and OH ions cancel out, leaving [Al(OH)3] as the sole term for Al, so the final solubility product expression is [Al(OH)3]^3. This can be expressed as [Al13+]^1[OH-]^3, which matches choice C.

Question 10

The solubility of lead(II)sulfate is 4.0 × 10^-2 g/L.What is the solubility product constant for lead(II)sulfate?

Accepted Answer

The solubility product constant (Ksp) for lead(II) sulfate, PbSO4, can be calculated from its solubility. Given the solubility is 4.0 × 10^-2 g/L, we first convert this to moles per liter (M) using the molar mass of PbSO4 (303.26 g/mol). Solubility in mol/L = 4.0 × 10^-2 g/L / 303.26 g/mol ≈ 1.32 × 10^-4 M. Since PbSO4 dissociates into Pb^2+ and SO4^2- in a 1:1 ratio, the concentrations of Pb^2+ and SO4^2- are each 1.32 × 10^-4 M. The Ksp = [Pb^2+][SO4^2-] = (1.32 × 10^-4)^2 ≈ 1.7 × 10^-8.

Question 11

What is the solubility product expression for La₂(CO₃)₃?

Accepted Answer

The correct expression for the solubility product of La2(CO3)3 is Ksp = [La^3+]^2[CO3^2-]^3, reflecting the stoichiometry of the dissociation into 2 La^3+ ions and 3 CO3^2- ions.

Question 15

The solubility of silver(I)carbonate is 3.6 × 10^-2 g/L.What is the solubility product constant for silver(I)carbonate?

Accepted Answer

The solubility product constant for a salt AB is given by the expression: 
Ksp= [A+]m[B-]n 
where m and n are the coefficients of the ions in the dissociation equation of the salt AB.

For silver(I)carbonate, the dissociation equation is: 
Ag2CO3 (s) ↔ 2Ag+ (aq) + CO3^2- (aq)

Therefore, 
Ksp = [Ag+]^2[CO3^2-]

The solubility of silver(I)carbonate is given as 3.6 × 10^-2 g/L.

The molar mass of Ag2CO3 = (2×107.87) + 12.01 + (3×16.00) = 331.75 g/mol

Therefore, the concentration of Ag2CO3 in mol/L is: 
(3.6 × 10^-2 g/L) / (331.75 g/mol) = 1.09 × 10^-4 mol/L

Since 1 molecule of Ag2CO3 gives 2 Ag+ ions and 1 CO3^2- ion, 
[Ag+] = 2 × (1.09 × 10^-4) = 2.18 × 10^-4 mol/L 
[CO3^2-] = 1.09 × 10^-4 mol/L

Substituting these values in the expression for Ksp, we get: 
Ksp = (2.18 × 10^-4)^2 × (1.09 × 10^-4) = 5.4 × 10^-12

Rounded to two significant figures, the answer is 11 × 10^-12 or 1.1 × 10^-11. 
Therefore, the best choice is B.

Question 16

What is the solubility product expression for Tb₃(PO₄)₄?

Accepted Answer

Option E has the correct stoichiometric coefficients for Tb and POS ions and matches the required formula of the compound given in the question.

Question 19

What is the solubility product expression for Pb(IO₃)₄?

Accepted Answer

The solubility product expression should include the concentration of the solid compound, which here is Pb(IO₃)₄. The correct expression should also include the concentrations of the ions that make up the solid compound, raised to their stoichiometric coefficients in the balanced chemical equation. Option D includes all of these components and is therefore the correct choice.
