Question

in electrolysis of water what is the composition of electrodes rod?

Answer 1

Answer:

The platinum or carbon electrodes are inert. You need inert (non–reactive) electrodes like platinum (left) and much cheaper carbon (graphite electrodes, right). In the simple electrolysis cell, the graphite (carbon) electrodes are, through a large rubber bung, 'upwardly' dipped into an solution of acidified water.
