Question

Blowing into lime water chemical equation and word equation

CLASS - 7th​

Answer 1

Answer:

calcium carbonate + water + carbon dioxide → calcium bicarbonate

CaCO3(s)+H2O(l)+CO2(g)→Ca(HCO3)2(aq)

The calcium bicarbonate produced is far more water-soluble, so the milky colour disappears as it dissolves.

If we consider the total result of these two reactions, we can produce the overall equation:

calcium hydroxide + carbon dioxide → calcium bicarbonate

Ca(OH)2(aq)+2CO2(g)→Ca(HCO3)2(aq)
