Question

Factors responsible for corrosion

Answer 1

Answer:

Presence of impurities in metals: Speed of corrosion increases with.

Presence of electrolyte: Electrolytes present in water also increases.

Position of metals in e.m.f. series: Highly reactive metals undergo.

Presence of carbon dioxide in water: Presence of carbon dioxide in.

Answer 2

1.More the reactivity of metal, the more will be the possibility of the metal getting corroded.

2.The impurities help in setting up voltaic cells, which increase the speed of corrosion

3. Presence of electrolytes in water also increases the rate of corrosion

4. Presence of CO2 in natural water increase corroding.

5.When the metal surface is coated with layers of metals more active than the particular metal, then the rate of corrosion is retarded.
