Which law relates the mass of a substance deposited at an electrode to the quantity of electricity passed?
- A.Faraday's law of electrolysis
- B.Kohlrausch's law
- C.Nernst equation
- D.Ohm's law
Show correct answer & step-by-step solution
Correct answer: A — Faraday's law of electrolysis
Solution
- Faraday's laws state that the mass of substance deposited is proportional to the charge passed.
- Kohlrausch's law deals with molar conductivity at infinite dilution.
- The Nernst equation relates cell potential to concentration.
- Ohm's law relates voltage, current, and resistance.
- Hence the answer is (A).
