Calculate the pH of 0.01 M solution of `NH_(4)CN.` The dissociation constants `K_(a)` for `HCN=6.2xx10^(-10)and K_(b)` for `NH_(3)=1.6xx10^(-5).`

Explanation

To calculate the pH of a 0.01 M solution of ammonium cyanide (NH₄CN), we can follow these steps:

### Step 1: Identify the components of the salt
Ammonium cyanide (NH₄CN) is a salt formed from the weak acid (HCN) and the weak base (NH₃).

### Step 2: Write the formula for pH of the salt solution
For a salt derived from a weak acid and a weak base, the pH can be calculated using the formula:
\[
