What happens when limestone comes in contact with an acid? Why?
1 Answer
The limestone dissolves to form a salt (in the chemical sense), water, and carbon dioxide.
Explanation:
Limestone is mainly composed of calcium carbonate.
In chemistry, acids and metal carbonates react to form a metal salt, water and carbon dioxide.
So with, for example, hydrochloric acid and calcium carbonate,
Which results in calcium chloride, water and carbon dioxide being formed.
Since everything that is produced is either a liquid, a gas, or soluble salt, which ends up simply evaporating or flowing off as runoff, the former insoluble limestone rock will appear to dissolve and erode
