Question

Which of the following salts is least soluble?
Answer
(A) Ag2CO3 Ksp = 8.4 ´ 10-12
(B) Ag2CrO4 Ksp = 1.1 ´ 10-12
(C) Agl Ksp = 1.5 ´ 10-16
(D) AgBr Ksp = 5.4 ´ 10-13

Answer 1

The higher the Ksp, the more soluble the compound is.

Answer 2

What do you think based on the above info?

Answer 3

I'd have to assume A @JoannaBlackwelder

Answer 4

That is the highest number, which is the most soluble, not the least soluble.
