Question

why electrode is taken of carbon during electrolysis​ to separate h2o

Answer 1

The carbon rod taken is nothing but graphite it is taken during electrolysis process becauseGraphite is an electric conductor, consequently, useful in such applications as arc lamp electrodes. It can conduct electricity due to the vast electron delocalization within the carbon layers (a phenomenon called aromaticity). These valence electrons are free to move, so are able to conduct electricity.

Answer 2

Here is ur ans

Bcoz electrode can conduct electricity..

Hope it helps
