Question

Which of the following statements regarding corrosion is true?

• A. Presence of electrolytes doesn't affect the rate of corrosion
• B. Presence of impurities doesn't affect the rate of corrosion
• C. Strains in metals affect the rate of corrosion
• D. Corrosion does not depend on the reactivity of the metal.

Answer 1

The correct option is C Strains in metals affect the rate of corrosion

More active metals are readily corroded. Presence of impurities in metals enhances the chances of corrosion. Corrosion takes place rapidly at bends, scratches, nicks and cuts in the metal. Electrolytes, if present, also increase the rate of corrosion.
