Question

State true or false - Metal corrodes due to salts

Answer 1

Depends. Some salts can corrode metals (if water is present), but more commonly, it's acids or oxygen that corrode metal. Strong bases can also corrode metal, under the right conditions.

Answer 2

Answer:

True

Explanation:

Metal in water is an electrolyte.

In the presence of water, salt accelerates the reaction.

This happens because salt increases water conductivity thereby increasing the number of ions in water.

Oxidation becomes higher when the number of ions increase in water.

Oxidation wears out metal thereby causing corrosion.

We can therefore conclude that it is true that metals corrode due to salt.
