When calcium hydroxide is dissolved in water, it dissociates to give calcium and hydroxide ions.
Ca(OH)₂(s) + aq → Ca²⁺(aq) + 2OH⁻(aq)
Due to the presence of hydroxide ions, the solution of calcium hydroxide is alkaline.
Ca(OH)₂(s) + aq → Ca²⁺(aq) + 2OH⁻(aq)
Due to the presence of hydroxide ions, the solution of calcium hydroxide is alkaline.
