What is the pH of acid rain?

Answer 1

Acid rain has a very low pH ranging between 5 and 6. It occurs due to oxides of sulphur and nitrogen or any other harmful chemicals present in polluted air that are mixed with water vapours.

When rain falls through contaminated air, it comes into contact with various chemicals, including sulfur and nitrogen, which combine with water vapor to form acid rain, which has a pH significantly lower than that of regular water.

HARMFUL AFFECTS OF ACID RAIN: It can kill fish and other aquatic life, upsetting the balance of the ecosystem; it can destroy buildings, statues, and other objects; it can damage trees and wash away nutrients from the soil.
