What is meant by disproportionation of an oxidation state ? Give an example

Explanation

**Step-by-Step Text Solution:**

1. **Definition of Disproportionation:**
Disproportionation is a chemical reaction in which a single substance is simultaneously oxidized and reduced, resulting in the formation of two different products with different oxidation states.

2. **Understanding Oxidation States:**
In a disproportionation reaction, the substance undergoing the reaction has an oxidation state that is unstable. This instability leads to the substance breaking down into two products: one with a higher oxidation state and another with a lower oxidation state.
