Question

Fill in the blanks:
________ is the purest form of natural water.

Answer 1

Hint: We get the purest form of natural water from the wonderful hydrological cycle, that is water cycle. The natural spring waters on earth are all contaminated with traces of organic and inorganic chemicals.

Complete step by step solution:
All the natural water bodies on Earth are contaminated with chemicals from a small to a large extent. The purest form of natural water is deprived of any contaminants including salts, minerals, particles or chemicals. Such pure water can be achieved in laboratories by the method of distillation. Distillation is the process of vaporizing water to form water vapours and then condensing it to reform liquid water which is devoid of previous contaminants. Nature has a very beautiful way of doing this, which is by the process of advection, evaporation, condensation and precipitation. This beautiful cycle is known as the water cycle. This produces the purest form of natural water, rain. It is free of minerals and other salts. When the water is evaporated from different water bodies on the Earth, it leaves behind all the impurities and forms the cloud.

Hence, the purest form of natural water on Earth is rain water.

Note: Remember that the spring water and underground water contain some impure chemical traces in them. Rain water is free from all these impurities and hence it is the purest form of natural water on the planet.
