Question

Study the diagram given below and answer the questions that follow:
(1) Give the names of electrodes A and B.
(2) Which electrode is the oxidising electrode?

Answer 1

(1) In the given diagram,

A- Anode
B- Cathode

• In electrolytic cell, cathode is negatively charged electrode connected to the negative terminal of the battery and anode is positively charged electrode connected to the positive terminal of the battery.

(2)

• In electrolytic cell, the electrode at which oxidation takes place is called anode.
• Thus,Electrode (A) is the oxidising electrode.
