Give the disproportionation reaction of `H_(3)PO_(3)`.

Explanation

To determine the disproportionation reaction of H₃PO₃ (phosphorous acid), we need to understand what a disproportionation reaction is. A disproportionation reaction is a type of redox reaction in which a single substance is simultaneously oxidized and reduced, resulting in the formation of two different products.

### Step-by-Step Solution:

1. **Identify the Oxidation States**:
In H₃PO₃, phosphorus (P) has an oxidation state of +3.

2. **Determine Possible Products**:
