In Faraday's law of Electrolysis, what does "Z" represents in the formula m =Zit?
Answer & explanation
Correct answer: option 2
Faraday's first law of electrolysis states that the mass of substance deposited or liberated at any electrode is directly proportional to the charge passed.
m α q
m = Zq
m = Zit
where Z is electrochemical equivalent ; Z = \(\frac{\text{Atomic weight}}{nF}\)
