Acids give which type of ions when dissolved in water?

Answer and explanation

Correct answer: Hydrogen ions

The governing concept is the Arrhenius description of acids. When an acid dissolves in water, it increases the concentration of hydrogen ions, commonly represented as H⁺; therefore option A is correct. In water, these ions are associated with water molecules as hydronium, H₃O⁺. Hydroxide ions are characteristic of bases, while sodium and calcium ions are not produced by every acid.
