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.
It is a physical change as you can change it back.
Yes, dissolving sodium hydroxide in water is a physical 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.
Dissolving is a physical process.
Dissolution, meaning dissolving into a liquid form. It is a chemical reaction that begins with water covering a corner of the salt. The corner chlorine starts to leave the crystal and water bonds form. As the chlorine leaves more water molecules are left behind. The chlorine becomes fully solvated then the salt does the same.

Dissolving tablets is a physical change, as they can be distilled out again.

Dissolving in water is a physical change.
Dissolving sugar in water is a physical change. If you let the water evaporate, the sugar will be left behind. Evaporation is a physical process, not chemical.
