physical
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.
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.
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.
Salt water is an example of a mixture. It is a solution made up of salt dissolved in water, without undergoing a chemical reaction. The components of salt and water can be separated by physical means such as evaporation.
The salt dissolves in the water and the sand does not.
Physical. It is a mixture of salt and water. No chemical change has taken place.
When salt is mixed with water, a physical change occurs. The salt dissolves in the water, forming a homogeneous mixture called a solution. The chemical composition of the salt and water remains the same.

Physical
Salt water is a physical separation because the salt dissolves in the water, creating a homogeneous mixture. The salt molecules do not chemically combine with the water molecules and can be separated through physical means, such as evaporation or filtration.
