Calculate the solubility of `AgCN` in a buffer solution of `pH 3.0`. Assume that no cyano complex is formed `K_(sp) AgCN = 2.2 xx 10^(-16), K_(a) HCN = 6.2 xx 10^(-10)`.

Explanation

To calculate the solubility of `AgCN` in a buffer solution of `pH 3.0`, we will follow these steps:

### Step 1: Write the Dissociation Reactions
AgCN dissociates in water as follows:
\[ \text{AgCN (s)} \rightleftharpoons \text{Ag}^+ (aq) + \text{CN}^- (aq) \]

HCN dissociates in water as follows:
\[ \text{HCN (aq)} \rightleftharpoons \text{H}^+ (aq) + \text{CN}^- (aq) \]
