(a) Cations are positively charged ions. During electrolysis, they are attracted to and discharged at the cathode.
(b) A labelled electrolytic cell is shown below.
A simple electrolytic cell with anode, cathode, electrolyte and d.c. power supply.
The anode is connected to the positive terminal of the d.c. supply, while the cathode is connected to the negative terminal. Cations move towards the cathode and anions move towards the anode through the electrolyte.
