This question isn't very complete, but if you meant what is the solute or solvent, the water would be the solvent because there is more water than salt. In this case, the salt is the solute. If there...
The density increases as the mass of the solution increases but its volume remains the same.
Entropy increases
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.
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.
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 salt in soup is a physical change.
All physical changes are reversible because the molecules do not undergo change in any chemical reaction even in in the change in the state of matter. NaCl is a salt compound and each molecules gets easily dissolved in water and the salt recovered by evaporation of water.
Dissolving salt in water is a physical change- no chemical reaction took place. If the water evaporates, the salt is still there.
A match burning is a chemical change. Salt dissolving in water is a physical change.
It is a physical change. If it was a chemical change you would probably see fizzing. stefan boniaby
Dissolving tablets is a physical change, as they can be distilled out again.
Dissolving is a physical process.
No. It is a physical change.
Dissolving in water is a physical change.
Dissolving in water is a physical change.
Dissolving in water is a physical change.
Dissolving salt in water is an example of a physical change. Although the ions of sodium and chlorine separate when the salt dissolves, no chemical reaction takes place.
