How will you distinguish between the following isomer pairs?
(i). `[Cr(NH_3)_5Br]SO_4` and (ii). `Cr(NH_3)_5(SO_4)]Br`

Explanation

To distinguish between the isomer pairs `[Cr(NH_3)_5Br]SO_4` and `Cr(NH_3)_5(SO_4)]Br`, we can analyze their ionization behavior in solution. Here's a step-by-step solution:

### Step 1: Identify the complexes
We have two complexes:
1. `[Cr(NH_3)_5Br]SO_4`
2. `Cr(NH_3)_5(SO_4)]Br`

### Step 2: Determine the ionization of the first complex
