Answer to Question #68168 in Biochemistry for Snigdha
How can acid rain be neutralized naturally?
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.
