Which type of ions do bases produce in water?
Answer and explanation
Correct answer: Hydroxide ions
The governing concept is the Arrhenius description of bases. A base produces hydroxide ions, OH⁻, in aqueous solution; these ions account for its alkaline properties. Hence option B is correct. Hydrogen ions are associated with acids, while chloride and carbonate ions may be present in particular salts but are not the defining ions produced by every base. The answer refers to the general school-level definition.
