`overset(V) (Cr) O_(4)^(3-)` in acidic medium undergoes disproportionation to form `"…................"` and `"…..................."`.

Explanation

To solve the question regarding the disproportionation of \( \text{CrO}_4^{3-} \) in acidic medium, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Disproportionation Reaction**:
Disproportionation is a type of redox reaction where a single substance is both oxidized and reduced, resulting in two different products. In this case, we are looking at \( \text{CrO}_4^{3-} \).

2. **Identify the Oxidation States**:
...
