Which ions do acids give when dissolved in water?

Answer and explanation

Correct answer: Hydrogen ions

The governing concept is the ionisation of acids in aqueous solution. Acids produce hydrogen ions in water; more precisely, these hydrogen ions associate with water molecules to form hydronium ions, H₃O⁺. This is responsible for acidic behaviour and low pH. Therefore, option A is correct. Hydroxide ions are characteristic of bases, whereas sodium and carbonate ions occur only when particular salts or compounds dissolve.
