Question

If hydrogen is a gas then it should attract anode electrode but it attracts cathode electrode.why?


Solution

This is a highly unstable configuration,and therefore immediately reacts with another hydrogen atom to produce H2, molecular hydrogen gas. At the other electrode (the anode), oxidation occurs. The OH– ions are attracted to the positive electrode where they are oxidized to form oxygen gas (O2) and hydrogen ions (H+).
