Salt dissolving in water is a physical change. true or false

The correct answer is True.

Salt dissolving in water is a physical change.

In physical change matter does not undergo any change in its chemical composition. In chemical change matter undergoes change in its chemical composition.

When salt (NaCl) dissolves in water it undergoes a change in the state of matter i.e., it gets converted from the solid state to the aqueous state.

Solid NaCl dissociates in water to form Na⁺ cation and Cl⁻ anion. Both the ions get hydrated i.e., surrounded by water molecules.  

NaCl(s) + H₂O--> Na⁺ (aq) + Cl⁻(aq)

NaCl does not undergo any change in its chemical composition, it simply splits into Na⁺ cation and Cl⁻ anion.
