Why must an acid dissolve in water to show its acidic properties?

Answer and explanation

Correct answer: To form hydrogen ions

Acids display their characteristic properties in aqueous solution because water allows their molecules to ionise and produce hydrogen ions, more accurately represented as hydronium ions, H₃O⁺. These ions cause acidic behaviour, including litmus change and reaction with suitable substances. Without water, the ions are not produced freely, so the acid does not show the usual aqueous properties. Therefore option A is correct.
