(a) What is electrolysis?
(b) A current of 2A is passed through a copper voltameter for 5 minutes. If the electrochemical equivalent of copper is 3.27 x 10(^{-7}) kg. Determine the mass of the corper deposited.
Explanation
(a) Electrolysis is the decomposition of an electrolyte into ions by passing current through the electrolyte.
(b) Mass of copper deposited M = zlt
= 3.27 x 10(^{7}) x 2 x 300 = 1.962 x 10(^{-4}) kg
