Solution
The correct option is D equivalent masses
The masses of different substances deposited or liberated, when the same quantity of current is passed through different electrolytes, connected in series are proportional to their chemical equivalent masses.
Consider three different electrolytes, AgNO3,CuSO4,andAl(NO3)3 solutions, connected in series. The same quantity of current is passed through them, then the masses of Ag, Cu, and Al, deposited on their respective • electrodes would be directly proportional to their equivalent masses. Atomic mass of the element
