Properties of quicklime

• Chemical formula: CaO

• Appearance: White to greyish solid lumps or powder

• Nature: Strongly alkaline and corrosive

• Reaction with water: Highly exothermic (releases heat), producing slaked lime (calcium hydroxide):

CaO+H2O→Ca(OH)2+heat\text{CaO} + \text{H}_2\text{O} \rightarrow \text{Ca(OH)}_2 + \text{heat}CaO+H2​O→Ca(OH)2​+heat
