Answer to Question #68168 in Biochemistry for Snigdha

Question

How can acid rain be neutralized naturally?

Answer 1

There is carbon dioxide in the air. It reacts with water to form HCO3- anion.
The acid rain contains hydronium ion H3O+. These two ions react each other.
H3O+ (aq) + HCO3-(aq) → H2O(l) + CO2(g)
So, acid can be neutralized by bicarbonate anion that forms from carbon dioxide.
