Concept explainers
Interpretation:
Three ways to protect metals from corrosion are to be mentioned.
Concept introduction:
Corrosion of metals under the action of moisture air and other corrosive factors is known as rusting. To prevent corrosion or rusting, various methods like galvanization, paint, oil coating etc.
Answer to Problem 51A
Correct answer: Three ways in which metals can be protected from corrosion are:
- Plating with non corrosive metals like stainless steel or aluminum.
- Coating with paint or oil
- Galvanization with zinc
Explanation of Solution
- Plating with non corrosive metals protects the inside metal from exposure.
- Coating with paint or oil prevents moisture from reaching the metal therefore preventing corrosion.
- Zinc acts as a corrosion inhibitor by getting oxidized in place of the metal.
Metals can be protected from corrosion by metal plating, oil or paint coating, or by galvanization.
