In the electrolysis of water,
Why is the volume of gas collected at one electrode double than the other?

Explanation

**Step-by-Step Solution:**

1. **Understanding Electrolysis of Water**: Electrolysis of water involves splitting water (H₂O) into hydrogen (H₂) and oxygen (O₂) gases using an electric current.

2. **Identifying the Reactions at Electrodes**:
- At the **cathode** (negative electrode), reduction occurs. The reaction can be represented as:
\[
2H^+ + 2e^- \rightarrow H_2 \text{ (hydrogen gas)}
