Mixing sand and salt is it a chemical or physical change

Mixing of salt is physical change.

Explanation:

Mixing of salt is physical change because no chemical reaction occur between them. Sand is non polar while salt is polar.

Physical Change:

The changes that occur only due to change in shape or form but their chemical or internal composition remain unchanged.

These changes were reversible.

They have same chemical property.

These changes can be observed with naked eye.

Chemical change:

The changes, that occur due to change in the composition of a substance and result in a different compound is known as chemical change.

These changes are irreversible

These changes occur due to chemical reactions

These may not be observed with naked eye
