Question:

What is the voltage at which electrolysis of brine takes place?

Options:

< 2.2 V

> 2.2 V

2.2 V

Brine cannot be electrolyzed

Correct Answer:

> 2.2 V

Explanation:

The minimum potential difference needed to electrolyze brine is 2.2 V, according theoretical estimates. However, practical electrolysis needs an emf larger than 2.2 V due to overvoltage.
