Calcium Bicarbonate Structure
On heating, calcium bicarbonate decomposes to calcium carbonate, carbon dioxide and water <8>.
Ca(HCO3)2 = CaCO3 + CO2 + H2O
It reacts v hydrochloric acid to produce calcium chloride, carbon dioxide and water <9>.
Ca(HCO3)2 + 2HCl = CaCl2 + 2CO2 + 2H2O
It reacts v sulfuric acid to develop calcium sulfate, carbon dioxide and also water <10>.
Ca(HCO3)2 + H2SO4 = CaSO4 + 2CO2 + 2H2O
Calcium bicarbonate reacts with nitric mountain to give calcium nitrate, carbon dioxide and also water <12>.
Ca(HCO3)2 + 2HNO3 = Ca(NO3)2 + 2CO2 + 2H2O
