Chemical equations relating to quicklime, hydrated lime and limestone As long as it's relevant, Chemical equations for related reactions And the purpose, nature, etc. This part doesn't hold very well. Chemical equations relating to quicklime, hydrated lime and limestone As long as it's relevant, Chemical Equations for Related Reactions And the purpose, nature, etc. This part doesn't hold very well.
All of them are white solid quicklime: CaO slaked lime: Ca (OH)2 limestone: CaCO3CaO+H2O=Ca (OH)2 reaction releases a large amount of hot Ca (OH)2+CO2=CaCO3 H2O. This reaction can be used to test carbon dioxide CaCO3=high temperature=CaO+CO2↑(industrial production of CO2) CaCO3+2HCl=CaCl2+H2O+CO2↑(experiment).
