(a) State two applications of electrolysis.
(b) Explain what is meant by the electrochemical equivalent of copper is 3.3 x 10\(^{-7}\) kgC\(^{-1}\)
(a) Applications of electrolysis:
— Electrotyping
— Electroplating
— Purification of metals
— Extraction of metals
— Callibration of ammeter
(b) It means that when a charge of one coulomb IC is passed through a copper voltameter 3.3 x 10\(^{-7}\) kg of copper is on the cathode.
