Write a chemical reaction in which the iodide ion replaces the diazonium group in a diazonium salt.

Explanation

To write the chemical reaction in which the iodide ion replaces the diazonium group in a diazonium salt, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Diazonium Salt**:
The diazonium salt can be represented as C6H5N2Cl, where C6H5 is the phenyl group (benzene ring) and N2Cl is the diazonium group.

2. **React with Potassium Iodide (KI)**:
