Problem

Ksp = 6.3 x 10-5 for the following hypothetical equation. Each of the following mixture is prepared with the indicated molarity of A2+ and B3- at 95°C and then allowed to cool to room temperature. Which of the mixtures would produce a precipitate of A3B2?

A3B2 (s)  ⇌  3 A2+ (aq) + 2 B 3- (aq)

a. [A2+] = 0.036 M and [B 3-] = 0.300 M

b. [A2+] = 0.272 M and [B 3-] = 0.042 M

c. [A2+] = 0.150 M and [B 3-] = 0.028 M

d. [A2+] = 0.086 M and [B 3-] = 0.895 M

e. [A2+] = 0.682 M and [B 3-] = 0.003
