Severe corrosion of metals occurred when coupled with platinum

severe-corrosion-of-metals-occurred-when-coupled-with-platinum

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.

A. True

B. False

I have been asked this question in an international level competition.

Enquiry is from Modern Theory Applications topic in chapter Modern Theory Applications of Corrosion Engineering

Correct answer is A. True

To elaborate: 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.
