Question

The solubility of $A{g}_{2}C{O}_3$ in water is $5520\mu g{L}^{-1}.K_{sp}$ of $A{g}_{2}C{O}_3$ is $(Ag=108)$

• A. $4.0\times 10^{-10}$
• B. $8.0\times 10^{-15}$
• C. $3.2\times 10^{-14}$
• D. $1.6\times 10^{-11}$

Answer 1

Answer: (C)

Solubility, $S=\frac{5520\times 10^{-6}}{276}=2\times 10^{-5}M$
$K_{sp}=4S^3=4\times {\left(2\times {\left(10\right)}^{-5}\right)}^3=3.2\times {\left(10\right)}^{-14}$
