Question

Write with an equation what happens when extra carbon-di-oxide gas is sent to lime water after a short time​

Answer 1

Answer:

An experiment commonly used to demonstrate the interaction of CO2 and Ca(OH)2 is as follows.

Hydrochloric acid and calcium carbonate in the left test tube.

Resultant carbon dioxide passed through limewater in the right tube, producing a milky solution due to precipitation of the insoluble suspension of calcium carbonate:

Ca(OH)2(aq) + CO2(g) → CaCO3(s) + H2O(l)

If excess CO2 is added: the following reaction takes place:

CaCO3(s) + H2O(l) + CO2(g) → Ca(HCO3)2(aq)

The milkiness disappears since calcium bicarbonate is water-soluble.
