You get a mixture of salt and sand. Nothing more happens.
it is a physical change. when salt and water is mixed . salt dissolves in water. here salt is not disappearing anywhere. its state is changing. chemical change means , once its reacted it cannot be regained . but here even though it is dissolved through evaporation we can regain the dissolved salt. its just a physical change.
Physical
When salt is mixed in with water, they form a solution. Salt is the solute, and water is the solvent.
For example melting and boiling of salt are physical processes.
This is a physical change because any reaction occur.
Chemical
The salt dissolves in the water and the sand does not.
It is made from the salt that is mixed in with the sand.

A mixture of salt and sand is an example of a physical change since the process is reversible.

Undissolved salt is salt that has not been dissolved in water, e.g rock salt or cooking salt.
It is a chemical change. The make up of the actual solution has changed, so it is chemical. A physical change is when something looks different than it did before. An iron bar goes through a physical change when it is made into a sword.
Physical
Mixing salt and pepper is a physical change
Solubilization of salt in water is a physical change.
