faraday's first law

Question

Faraday's first law states mass deposited is proportional to:

RankGuru · Accepted Answer

1. **Statement**: The mass ($m$) of any substance deposited or dissolved at an electrode during electrolysis is directly proportional to the quantity of **electricity (charge)** passed through the electrolyte.
2. **Formula**: $m \propto Q$.
3. **Charge Relation**: Since $Q = I \cdot t$ (Current $	imes$ Time), we can write $m = Z \cdot I \cdot t$.
4. **Constant**: $Z$ is the electrochemical equivalent of the substance.
5. **Dependence**: It depends on both current and time, which together constitute the total **charge passed**.
