Acid rain is a mixture of:

  1. sulphuric acid with hydrochloric acid and nitric acid with nitrous acid

  2. sulphuric acid with sulphurous acid and nitric acid with hydrochloric acid

  3. sulphuric acid with sulphurous acid and nitric acid with nitrous acid

  4. sulphuric acid with nitrous acid and nitric acid with sulphurous acid
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

When oxides of sulphur and nitrogen emitted by the industries, react with the moisture present in the atmosphere they form acids.

The acids formed by sulphur oxides are sulphuric acid with sulphurous acid and the acids formed by nitrogen oxides are nitric acid with nitrous acid.
These acids are responsible for the acidity of rains. The pH of acid rain is 5.5
Thus, the correct answer is option (C).

What occurs when acidic oxides generated of carbon, nitrogen and sulphur due to burning of fossil fuels come in contact of rain?

  1. Acid rain

  2. Basic Rain

  3. Normal Rain

  4. Hailstorms
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Acid rains are caused when the pollutants such as sulphur dioxide and nitrous oxide formed due to the burning of the fossil fuels are released in the atmosphere, where they travel upwards and mixes with oxygen, air and moisture to form pollutants called acidic oxide pollutants.

  3. Snow

  4. All of the above
