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 sodium carbonate a chemical change?
Dissolving sodium carbonate in water is a physical change, not a chemical change. This is because the chemical composition of sodium carbonate remains the same before and after dissolving.
Is dissolving sodium chloride a physical change?
Yes, dissolving sodium chloride in water is considered a physical change. This is because only the state of matter changes (solid to aqueous solution), and no new substance is formed.
Is dissolving powder into water a chemical change?
No, dissolving powder into water is a physical change, not a chemical change. The powder molecules are still the same chemical compounds as they were before dissolving, just dispersed in the water molecules.
Dissolving salt into water is it physical or chemical change?
This is a physical change. You can separate the salt and water by the physical process of distillation or evaporation where the water is boiled away and the salt is left behind.
Is dissolving NaCl in h2o a chemical change?
Dissolving NaCl in water is a physical change, not a chemical change. The NaCl molecules remain the same chemically, but the arrangement of the particles changes as they interact with water molecules.
Is cofee dissolving in water a physical or chemical change?
It is a physical change.
Is dissolving in water a chemical change?
Dissolving in water is a physical change.
Is dissolving gelatin in water a physical change?
Dissolution is considered a chemical phenomenon; but physical implication also exist.
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 dissolving sugar into water a chemical or a physical change?
It is a physical change.
Salt dissoved in water physical or chemical change?
Dissolving in water is a physical change.
Suger dissloves in water a physical or chemical change?
Dissolving in water is a physical change.
Is combining water and salt physical or chemical change?
Dissolving in water is a physical change.
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.
