Question

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 salt in water is a change that cannot be reversed.
• C. mixing salt in water is a permanent change.
• D. The mixing of salt in water is a change that can be reversed by evaporation

Answer 1

The correct option is D The mixing of salt in water is a change that can be reversed by evaporation

Separation of salt from the water solution can be done by evaporating the water from the solution gives back the salt.

Hence, mixing salt in water is a reversible change.
