Name the type of reaction that occurs at anode in an electrochemical cell. Give an example.

Explanation

### Step-by-Step Solution:

1. **Identify the Reaction at the Anode**:
In an electrochemical cell, the anode is the electrode where oxidation occurs. Oxidation is defined as the loss of electrons.

2. **Define Oxidation**:
Oxidation can be summarized as a process where a substance loses electrons, resulting in an increase in its oxidation state.
