Quick Lime: Chemical Reaction When Added to Water

Quick lime (calcium oxide) reacts strongly when added to water, producing slaked lime (calcium hydroxide) and releasing heat. This Quick Lime Reaction is widely used in construction, water treatment, and chemical industries due to its ability to form stable compounds and regulate pH levels.

What Happens Chemically When Quick Lime is Added to Water?

The reaction follows this chemical equation:

CaO+H2O→Ca(OH)2+HeatCaO + H_2O → Ca(OH)_2 + HeatCaO+H2​O→Ca(OH)2​+Heat

When quick lime is mixed with water:

• Heat is released as an exothermic reaction occurs.
• Steam may form due to high temperatures.
• A white, powdery or paste-like substance (slaked lime) appears as the reaction completes.

Why is the Quick Lime Reaction Important?

This reaction has several industrial uses:

• Construction: Used in cement, mortar, and plaster for strong, durable structures.
• Water Treatment: Helps neutralize acidity and remove impurities from wastewater.
• Industrial Manufacturing: Used in steel refining, glass production, and chemical processing.

Safety Precautions When Handling Quick Lime

• Avoid direct skin and eye contact to prevent burns.
• Use gloves, goggles, and protective clothing.
• Store in dry conditions to prevent unwanted reactions.
