Faraday's Second Law

Question

According to Faraday's second law, masses of different substances liberated by same charge are proportional to their:

RankGuru · Accepted Answer

1. **Statement**: When the same quantity of electricity is passed through different electrolytes connected in series, the masses of the substances produced at the electrodes are proportional to their **chemical equivalent weights ($E$)**.
2. **Equivalent Weight**: $E = \frac{	ext{Molar Mass}}{	ext{Valence factor }(n)}$.
3. **Ratio**: $\frac{m_1}{m_2} = \frac{E_1}{E_2}$.
4. **Link to Faraday constant**: Passing $1$ Faraday ($96485$ C) of charge always deposits $1$ equivalent weight of any substance.
