(b) Alloys

(c) Both commercially pure metal and alloys

(d) Neither commercially pure metals nor alloys

I have been asked this question in an interview for job.

This intriguing question originated from Prevention topic in chapter Corrosion Prevention of Corrosion Engineering

Answer 1

Correct answer is (a) Commercially pure metals

To elaborate: Commercially pure metal such as aluminum (99.5+ purity) is used for handling hydrogen peroxide. Alloys result in the decomposition of hydrogen peroxide due to the catalytic action of alloying elements.
