Which ion do bases give in water?
Answer and explanation
Correct answer: Hydroxide ion
In the Arrhenius model, a base is a substance that produces hydroxide ions, OH−, when dissolved in water. These ions account for the characteristic basic properties of the solution, so option B is correct. Hydrogen ions are associated with acids. Chloride and nitrate ions may be released by particular salts, but they are not the defining ions produced by every base in water.
