Question

electrolysis of acidified water using platinum electrodes gives hydrogen but why should we use only platinum electrodes???

Answer 1

We use platinum electode beacause it is an inert electrode which means that it does not take part in the overall reaction so H+ will get reduced and we will surely get hydrogen gas.

however,if we use some other metal electrode , there is a possibility that the metal will get reduced instead of H+ and we won't get hydrogen gas.
