Question

Rain water is considered the purest form of natural water. Explain the statement.

Answer 1

Rain water is considered to be the purest form of natural water as it is directly comes from the condensation of water droplets. In the presence of sun, the water evaporates from the seas, oceans , rivers (from all the natural open resources of water) leaving behind all the impurities and form the cloud. From there it is directly come to the earth in the form of rain.

But now a days environment is not clean and air is highly polluted with toxic gases which combines with the rain water making it acidic (known as acid rain).Hence rain water is no more the purest form of natural water.
