Can `NH_(4)Cl` be replaced by any other ammonium salt for the precipitation of group III cations?

Explanation

To determine if `NH₄Cl` can be replaced by any other ammonium salt for the precipitation of group III cations, we can analyze the properties of different ammonium salts and their effects on the precipitation process.

### Step-by-Step Solution:

1. **Understanding Group III Cations**:
Group III cations in qualitative analysis typically include ions such as Al³⁺, Fe³⁺, and Cr³⁺. These cations are precipitated as hydroxides or other insoluble compounds when treated with specific reagents.

2. **Role of Ammonium Chloride (NH₄Cl)**:
