Question

Water containing high salt concentration can be purified by
(a) Boiling
(b) UV radiation
(c) Filtration
(d) Reverse osmosis

Answer 1

Answer:

By Boiling(option B) ॥

Answer 2

Answer:

(d) Reverse osmosis

Explanation:

Water containing high salt concentration can be purified by the process of reverse osmosis. Reverse osmosis is an effective way to remove some unwanted molecules from the water. In the reverse osmosis process, water is let to pass through a membrane, which leads to the separation of water and salt.

Only boiling of water can't remove salt from it.  

Filtration is used to remove non-soluble material from the water, while UV radiation is used to make water free from germs.
