Acidified water is electrolysed by using carbon electrodes. What is produced at
negative carbon electrode

Explanation

To determine what is produced at the negative carbon electrode (cathode) during the electrolysis of acidified water, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Electrolysis Setup**:
- We are electrolyzing acidified water using carbon electrodes. Acidified water means water that has been mixed with an acid (like sulfuric acid) to increase the conductivity.

2. **Understand the Role of Electrodes**:
...
