Question

Definition (produces hydroxyl ions on dissolution in water)

(b) Ca(OH)₂ 🡪

Answer 1

• Bases produce hydroxide (OH^-) ions when dissolved in an aqueous solution.
• When calcium hydroxide is dissolved in water, it produces calcium ions along with hydroxide ions.
• The chemical equation for the given reaction is as follows:
• $\underset{\mathrm{Calcium}\mathrm{hydroxide}}{\mathrm{Ca}{\left(\mathrm{OH}\right)}_2\left(\mathrm{aq}\right)}\to \underset{\mathrm{Calcium}\mathrm{ion}}{{\mathrm{Ca}}^{2+}\left(\mathrm{aq}\right)}+\underset{\mathrm{Hydroxide}\mathrm{ion}}{2{\mathrm{OH}}^{-}\left(\mathrm{aq}\right)}$
