Salt can be separated from its solution (salt dissolved in water), because (a) mixing of salt in water is a change that can be reversed by heating and melting of salt (b) mixing of salt in water is a change that cannot be reversed (c) mixing of salt in water is a permanent change mixing of salt in water is a change that can be reversed by evaporation

Answer
- Solution:
(d): mixing of salt in water is a change that can be reversed by evaporation.
Salt can be separated from water solution by evaporating the water. Hence mixing of salt in water is a reversible change.
