Give chemical test for distinguishing between ` Fe^(2+) and Fe^(3+)` ions.

Explanation

To distinguish between Fe²⁺ (ferrous) and Fe³⁺ (ferric) ions, we can perform a simple chemical test using ammonium hydroxide (NH₄OH) or sodium hydroxide (NaOH). Here’s a step-by-step solution:

### Step 1: Prepare Solutions
- Take two separate test solutions: one containing Fe²⁺ ions (for example, ferrous sulfate, FeSO₄) and the other containing Fe³⁺ ions (for example, ferric chloride, FeCl₃).

### Step 2: Add Ammonium Hydroxide or Sodium Hydroxide
- To each solution, add a few drops of ammonium hydroxide (NH₄OH) or sodium hydroxide (NaOH).
