This is a physical change.
This is a an interesting example - it is considered to be physical because the salt can be recovered through evaporation. However the salt in solution is separated into ions which are solvated by water molecules- this could be argued as a chemical change.- as there are albeit weak interactions between the water and the ions.
Some salts dissolve and hydrolysis occurs, a "genuine" chemical reaction with water. An example is sodium acetate, (a salt of a weak acid), this dissolves to give a basic solution- this would be a chemical change. This is reversible - you can evaporate the water and get the salt back.

Is dissolving tables in salt water a physical change?
Dissolving tablets is a physical change, as they can be distilled out again.
Is dissolving in water physical or chemical?
Dissolving in water is a physical change because it only involves the separation of molecules within a substance without changing their chemical composition.
Is dissolving sodium chloride a chemical or physical change?
Dissolving sodium chloride in water is a physical change because the chemical composition of sodium chloride remains the same. The sodium and chloride ions are simply dispersed throughout the water, but they can still be recovered by evaporating the water.
Is dissolving common salt in water physical or chemical change?
Dissolving is a physical process.
Is the dissolving salt in water a chemical or physical change?
The dissolving of salt in water is considered a physical change, not a chemical change. This is because no new substances are being formed during the process; the salt molecules are simply breaking apart and dispersing throughout the water.
