In the electrolysis of acidulated water, it is desired to obtain hydrogen at the rate of 1 cc per second at NTP condition. What should be the current passed?

Explanation

To solve the problem of determining the current required to produce hydrogen gas at a rate of 1 cc per second during the electrolysis of acidulated water, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Electrolysis Process**:
- During the electrolysis of acidulated water, hydrogen gas is produced at the cathode. The reaction can be summarized as:
\[
2H^+ + 2e^- \rightarrow H_2
