i am looking for the same thing!
Mixing salt and water is a physical change, not a chemical change. The salt does not change its chemical composition when it dissolves in water, only its physical state.
Yes, salt dissolving in water is a physical change because it does not involve a change in the chemical composition of the salt. The salt molecules are simply dispersed in the water, but they remain the same chemical substance.
It is a physical change because the chemical composition of the salt and water does not change.

Solubilization of salt in water is a physical change.
Solubilization of salt in water is a physical change.
Making salt water to gargle for a sore throat is not a chemical change. This is because the salt can be extracted from the water.
Making salt water to gargle for a sore throat is not a chemical change. This is because the salt can be extracted from the water.
Dissolving salt in water is a physical change- no chemical reaction took place. If the water evaporates, the salt is still there.
It is a physical change because the chemical composition of salt and water do not change. You can separate the salt and water physically by allowing the water to evaporate, which leaves the salt.
A match burning is a chemical change. Salt dissolving in water is a physical change.
When salt is mixed in with water, they form a solution. Salt is the solute, and water is the solvent.
