Question

Which of the following is most soluble ?

• A. $B{i}_2{S}_3\left(K_{sp}=1\times 10^{-70}\right)$
• B. $MnS(K_{sp}=7\times 10^{-16})$
• C. $CuS(K_{sp}=8\times 10^{-37})$
• D. $A{g}_{2}S(K_{sp}=6\times 10^{-51})$

Answer 1

Answer: (B)

In all these compounds the $MnS$ is most soluble because its solubility product is maximum
