Question

Corrosion of iron takes place even in the solid ice.

(a) True

(b) False

This question was posed to me in unit test.

This intriguing question comes from Corrosion and its Classification topic in chapter Corrosion Principles of Corrosion Engineering

Answer 1

The correct answer is (b) False

To elaborate: Though ice is the solid form of water but it doesn’t conduct electrons. The function of an electrolyte is to transfers ions from one electrode to another. Thus, given statement is false. Corrosion needs an anode, a cathode and a conductive electrolyte.
