What is the correlation between limestone, quicklime, hydrated lime and calcium carbonate? Write the chemical equation for conversion
Lime: CaO
Hydrated lime: Ca (OH)2
The main component of limestone is calcium carbonate: CaCO3
Lime + water = hydrated lime:
CaO+H2O=Ca (OH)2(exothermic)
Hydrated lime + carbon dioxide = calcium carbonate
Ca (OH)2+CO2=CaCO3 H2O
CaCO3 heated:
CaCO3(heating)= CaO+CO2↑
What is the chemical formula of slaked lime, quicklime and limestone?
Hydrated lime: Ca (OH)2
Lime: CaO
Limestone: CaCO3
Calcination of limestone yields quicklime, a hydrated lime that reacts with water.
