Severe corrosion of metals occurred when coupled with platinum is due to the higher current density for hydrogen evolution but not due to the reversible potential of the platinum-platinum ion electrode.

Severe corrosion of metals occurred when coupled with platinum is due to the higher current density for hydrogen evolution but not due to the reversible potential of the platinum-platinum ion electrode. Correct Answer True

Severe corrosion of metals occurred when coupled with platinum is due to the higher current density for evolution but not due to the reversible potential of the platinum-platinum ion electrode. Notably, platinized platinum has the highest exchange current density for hydrogen evolution.
