Which of the following is not a method of prevention of corrosion?(a) Galvanization(b) Anti-rust solutions(c) Cathodic protection(d) HeatingI had been asked this question by my school principal while I was bunking the class.The query is from Electrochemistry in section Electrochemistry of Chemistry – Class 12

Answer»

Correct answer is (d) Heating

The best I can explain: Galvanization is the process of coating iron with zinc to prevent its oxidation. Anti-rust solutions are ALKALINE phosphate and alkaline chromate solutions. The alkalinity prevents the availability of hydrogen ions. Cathodic protection is the process of connecting the iron object to be PROTECTED to a more ACTIVE METAL either directly or through a wire.
