The solubility of AgCN in a buffer solution of $\displaystyle \mathrm{pH}=3$ is $\displaystyle x$. The value of $\displaystyle x$ is : [Assume : No cyano complex is formed ; $\displaystyle \mathrm{K}_{\mathrm{sp}}(\mathrm{AgCN})=2.2 \times 10^{-16}$ and $\displaystyle \mathrm{K}_{\mathrm{a}}(\mathrm{HCN})=6.2 \times 10^{-10}$ ]
Official answer
(4)
$\displaystyle 1.9 \times 10^{-5}$
