Question

The expression for the solubility product of $Ag_2CO_3$ will be :

• A. $K_{sp} = s^2$
• B. $K_{sp} = 4s^3$
• C. $K_{sp} = 27s^4$
• D. $K_{sp} = s$

Answer 1

Answer: (B)

$K_{sp} = 4s^3$

Answer 2

$Ag_{2}CO_{3} {<=>} \underset{\text{2s}}{2Ag}+\underset{s}{CO^{2-}_{3}}$ $K_{sp}=(2s)^{2}\times s=4s^{3}$
