Faraday's first law of electrolysis: amount of substance liberated at electrode is proportional to:
AVolume
BVoltage
CCharge passed (Q = I × t)
DTime only
Answer & Solution
Correct answer: C. Charge passed (Q = I × t)
m = (Q × M)/(n × F) where Q = It is charge, M = molar mass, n = electrons per ion, F = 96500 C/mol. Mass deposited is directly proportional to charge.
