Question

Write Faraday’s 2nd law of Electrolysis.

Hint:

The key idea of Faraday’s second law is the relationship between the amount of substance and the electric charge during electrolysis.

Answer 1

Step 1: Understand Faraday’s Second Law of Electrolysis.
Faraday’s Second Law of Electrolysis states that the amount of substance deposited or liberated at an electrode is directly proportional to the quantity of electric charge passed through the electrolyte. Mathematically, it is given as: \[ \frac{m_1}{m_2} = \frac{M_1}{M_2} \times \frac{Q_1}{Q_2} \] Where: - \( m_1 \) and \( m_2 \) are the masses of the substances deposited or liberated. - \( M_1 \) and \( M_2 \) are the molar masses of the substances. - \( Q_1 \) and \( Q_2 \) are the electric charges passed.
Step 2: Explanation.
This law helps in understanding how different substances react when electric current is passed through an electrolyte and how much of each substance is involved in the electrolysis process.
Final Answer: Faraday’s Second Law of Electrolysis relates the amount of substance deposited or liberated to the electric charge passed.
Final Answer: \[ \boxed{\text{Faraday’s 2nd Law states that the amount of substance deposited is directly proportional to the quantity of electric charge passed.}} \]
