How can be the following pair of isomers be distinguished from one another
I `[Co(NH_(3))_(6)][Cr(NO_(2))_(6)]` and
(II) `[Cr(NH_(3))_(6)][Co(No_(2))_(6)]`

Explanation

To distinguish between the two isomers, `[Co(NH₃)₆][Cr(NO₂)₆]` and `[Cr(NH₃)₆][Co(NO₂)₆]`, we can follow these steps:

### Step 1: Understand the Composition of Each Isomer
- **Isomer I**: `[Co(NH₃)₆]³⁺` and `[Cr(NO₂)₆]³⁻`
- **Isomer II**: `[Cr(NH₃)₆]³⁺` and `[Co(NO₂)₆]³⁻`

### Step 2: Prepare Aqueous Solutions
- Dissolve both isomers in water to create their respective aqueous solutions.
