Question

what is the formula of calcium carbonate in water

Answer 1

heya...........

Calcium carbonate doesn’t react with pure water, but it does react with carbonic acid, that is, water with dissolved carbon dioxide, to produce soluble calcium bicarbonate.

CaCO3 + CO2 + H2O → Ca(HCO3)2

That is how caves form in limestone, and how stalagmites and stalactites form from dripping water in those caves. The dissolved calcium bicarbonate is the principle mineral in hard water. It dissociates back to calcium carbonate when the water is boiled, causing lime scale.

Answer 2

hey mate here is ur ans
CaCO3+2H2O----->Ca(OH)2+H2O+CO2
when calcium carbonate reacts with water it gives calcium hydroxide water and carbon dioxide

I hope it helps you
