Chemical Properties & Reactions
Hydration Reaction
Hydrated lime is produced through the controlled hydration of quicklime: CaO + H₂O → Ca(OH)₂ + Heat
Carbonation Process
In atmospheric conditions, hydrated lime gradually absorbs carbon dioxide: Ca(OH)₂ + CO₂ → CaCO₃ + H₂O
Neutralization Reactions
Effectively neutralizes acids through hydroxide ion release: Ca(OH)₂ + 2HCl → CaCl₂ + 2H₂O
Precipitation Reactions
Forms insoluble compounds with various ions for water treatment: Ca(OH)₂ + Na₂SO₄ → CaSO₄ + 2NaOH
