The dissolution of the gas HCl itself is a physical process, no molecules being changed
but the dissolved molecules react more or less completely with water,
according to the acidic dissociation reaction (which is a chemical process):
HCl + H2O --> H3O+ + Cl-
It is a chemical change ....
Dissolution is a chemical process.
Dissolving sodium chloride in water is a physical change because the chemical composition of sodium chloride remains the same. The sodium and chloride ions are simply dispersed throughout the water, but they can still be recovered by evaporating the water.
Dissolution of sodium chloride in water is a chemical process.
The observation that hydrogen chloride is a gas at room temperature is a PHYSICAL property.
Dissolving is a physical change because the molecule of sodium chloride remain unchanged.
The chemical formula of sodium chloride is not changed by dissolution.
The dissolution of sodium chloride in water is considered a physical change because no new substances are formed - the sodium chloride remains as sodium and chloride ions in the water solution.
