Question

Distinguish between

Oxidation and Carbonation

Answer 1

	Oxidation	Carbonation
1.	Oxygen in the atmosphere reacts with the iron found in rocks.	Carbonation is the mixing of water with atmospheric carbon-di-oxide.
2.	It leads to the formation of iron oxide.	As a result, carbonic acid is formed.
3.	This process is known as oxidation.	Carbonation is important in the formation of caves, in the limestone region.
4.	It results in the weakening of rocks.	When the carbonic acid reacts with the carbonate rocks, the rocks get disintegrated.
