State Faraday's first law of electrolysis.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Concept of Electrolysis**: Electrolysis is a chemical process that uses electricity to drive a non-spontaneous reaction. It involves the decomposition of an electrolyte into its constituent ions.

2. **State Faraday's First Law of Electrolysis**: Faraday's first law states that the mass of an element deposited or liberated at an electrode during electrolysis is directly proportional to the quantity of electricity (charge) passed through the electrolyte.

3. **Mathematical Representation**: This relationship can be expressed mathematically as:
\[
