Answer 1

Answer - Boiling or evaporation

- When we add 2 spoons of salt in half cup water, it completely dissolves in the solution which can't be filtered or precipitated.

- We can separate salt from salt solution by 2 methods-

(1) Boiling-

When salt soln is heated on a stove water is disposed off, leaving the salt powder behind.

(2) Evaporation-

When salt soln is evaporated in open sunlight, water is evaporated off leaving the salt behind.

Hope this cleared your doubts.
