The solubility of AgCN in a buffer solution of pH = 3 is x. The value of x is : [Assume : No cyano complex is formed; Ksp(AgCN) = 2.2 $\times$ 10$-$16 and Ka(HCN) = 6.2 $\times$ 10$-$10]

Question

The solubility of AgCN in a buffer solution of pH = 3 is x. The value of x is : [Assume : No cyano complex is formed; K_sp(AgCN) = 2.2 $\times$ 10^$-$16 and K_a(HCN) = 6.2 $\times$ 10^$-$10]

1.9 $\times$ 10^$-$5

1.6 $\times$ 10^$-$6

2.2 $\times$ 10^$-$16

0.625 $\times$ 10^$-$6
