Can we add `NH_(4)OH` first and `NH_(4)Cl` later in the analysis of group III cations?

Explanation

To determine whether we can add ammonium hydroxide (NH₄OH) first and ammonium chloride (NH₄Cl) later in the analysis of group III cations, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Group III Cations**:
- Group III cations typically include Al³⁺, Zn²⁺, and Fe³⁺.

2. **Understand the Role of NH₄OH and NH₄Cl**:
