Quantitative Electrolysis Flashcards
1
Q
What is the mass of a substance proportionate to?
A
The mass of a substance produced at an electrode during electrolysis is proportional to the time over which a constant electric current is applied and the strength of the electric current.
(In other words, the amount of substance produced is proportional to the number of electrons transferred from anode to cathode.)
