Question

Adding salt to water, to make a salt solution, is a ____ process.

• A. reversible
• B. irreversible
• C. cannot say
• D. slow

Answer 1

The correct option is A

reversible

Preparation of salt solution is a reversible process as salt can be retrieved upon heating the solution, thus evaporating the water and leaving salt behind.

Moreover, the evaporated water can be converted back from vapour state to water by cooling (condensation). Thus both components are retrieved back and hence the process is reversible.
