Question

Name the gases which dissolve in rainwater before it reaches the ground. What harm can be caused by these gases?

Answer 1

Rainwater - It is a form of natural water that can be categorized under the surface water as it is received as rainfall from the clouds.

Gases that dissolve in rainwater before it reaches the ground:-

1. Oxygen
2. Nitrogen
3. Carbon dioxide

In areas having industries and regions which have recently observed volcanic eruptions the rainwater dissolves following gases from the atmosphere

1. Sulfur dioxide
2. Nitrogen dioxide

The harms caused by these gases:-

1. Carbon dioxide when dissolved in water forms Carbonic acid, this Carbonic acid reacts with Limestone and Marble and turns it yellowish in color and damages it.
2. Sulfur dioxide when dissolved in water forms Sulphuric acid which is a very corrosive and dangerous acid.
3. Nitrogen dioxide when dissolved in water forms Nitric acid that damages the proteins in the skin.
4. Sulfuric and Nitric acid together forms the acid rain and damage crops, and buildings, and if any human or animal comes in contact with it, they can suffer severe injuries.
