The solubility of AgCN in a buffer solution of pH}=3 is X.

Question:

The solubility of $\mathrm{AgCN}$ in a buffer solution of $\mathrm{pH}=3$ is $\mathrm{x} .$ The value of $\mathrm{X}$ is:

[Assume: No cyano complex is formed; $\mathrm{K}_{\mathrm{sp}}(\mathrm{AgCN})=2.2 \times 10^{-16}$ and $\mathrm{K}_{\mathrm{a}}(\mathrm{HCN})=6.2 \times 10^{-10}$ ]

  1. $0.625 \times 10^{-6}$

  2. $1.6 \times 10^{-6}$

  3. $2.2 \times 10^{-16}$

  4.  $1.9 \times 10^{-5}$
