Sodium chloride is dissociated in water, forming ions Na+ and Cl-.
Dissolution is a physical process because the chemical composition of salt (NaCl) remain unchanged; also the process is reversible.
chemical
When salt is mixed in with water, they form a solution. Salt is the solute, and water is the solvent.
Chemical change.
When an acid dissolves in water hydrogen ions bond with water to form hydronium ions, H3O+ When bases dissolve in water, hydroxide ions are formed, OH-
A chemical change occurs because compound is two elements put together so when they are separated it forms a new substance.

A physical change!

a change of stateIce melting is a physical change
a physical change called melting. It is also called a phase change.
I want to say physical change
When salt dissolves in water, it undergoes a physical change, not a chemical change. This is because the chemical composition of salt (NaCl) remains the same before and after dissolving in water. The salt molecules are simply dispersed in the water, forming a homogeneous mixture.
When salt is mixed in with water, they form a solution. Salt is the solute, and water is the solvent.
Jello dissolves faster in sugar not water.
