Explanation:
Detailed explanation-1: -An Arrhenius base is a compound that increases the OH− ion concentration in aqueous solution. Ionic compounds of the OH− ion are classic Arrhenius bases.
Detailed explanation-2: -Answer and Explanation: Calcium Hydroxide fulfills both definitions of basicity. It is both an Arrhenius base and Bronsted-Lowry base. Writing the chemical equation for the dissolution of calcium hydroxide, we find that it produces hydroxide ions in solution.
