Question

write the four factors responsible for the corrosion of iron.

Answer 1

Hi friends :-)

Following are the four factors responsible for corrosion of iron :

1. When iron comes in contact with moist air.

2. Presence of water.

3. When no paint or warnish applied to the iron.

4. If it is not cleaned regularly then it corrodes.

Hope that this answer will help you.

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