Which ions do bases produce in water?
Answer and explanation
Correct answer: Hydroxide ions
The governing concept is the Arrhenius definition of a base. A soluble base dissociates in water to produce hydroxide ions, OH⁻, which account for its basic behaviour; therefore option A is correct. Hydrogen ions are associated with acids. Nitrate and carbonate ions can be parts of particular salts or bases, but neither one is the ion that defines every base in water.
