Question

Anodes are continuously replaced during the electrolysis of Alumina by Hall Heroult's process- why?​

Answer 1

Answer:

The anode is renewed periodically as they get oxidized. (At the positive anode, oxygen gas is formed and at high temperature of the electrolysis cell it burns and oxidises away the carbon electrodes to form toxic carbon monoxide or carbon dioxide. So the carbon graphite electrode is regularly replaced )
