Calculate the solubility of `AgCN` in a buffer solution of `pH = 3`, Given `K_(sp) of AgCN = 1.2 xx 10^(-16)` and `K_(a)` for `HCN = 4.8 xx 10^(-10)`.

Explanation

To calculate the solubility of AgCN in a buffer solution of pH = 3, we need to follow these steps:

### Step 1: Determine the concentration of H⁺ ions
Given that the pH of the solution is 3, we can calculate the concentration of H⁺ ions using the formula:
\[ \text{[H⁺]} = 10^{-\text{pH}} \]
Substituting the value of pH:
\[ \text{[H⁺]} = 10^{-3} = 0.001 \, \text{M} \]
