For each of the salts below, match the salts that can be compared directly, using Ksp values, to estimate solubilities. a. Mg(OH)2
b. CaSO3
c. BaCrO4
d. CaS

1. copper (II) sulfide
2. zinc hydroxide

1 - Salts required  that can be compared directly, using Ksp values, to estimate solubilities for copper (II) sulfide are - (Option b) , (Option c) and (Option d)

2 - Salts  that can be compared directly, using Ksp values, to estimate solubilities for zinc hydroxide are - (Option a)

Explanation:

values can be used to compare the solubility of salts that produce ions in a 1:1 ratio.

Because the salts , and  have a 1:1 ion ratio, the solubilities of options b, c, and d can be compared to salt 1.

Values can be used to compare the solubility of salts that produce ions in a 1:2 or 2:1 ratio.

  2. dissociates into ions in ratio 1:2 .

Because the ions in the salt are in a 1:2 ratio, the solubility of salt 2 can be compared to that of salt 'a'.

Hence , Salt 1 is matched with options b , c , d.

              Salt 2 is matched with option a.
