Question

. Carbon dioxide gas is passed through lime water to form precipitate of calcium carbonate.

Answer 1

CO2+Ca(OH)2==>CaCO3+H2O

Answer 2

Answer: The equation for this reaction is given below.

Explanation:

Lime water is the solution of calcium hydroxide in water. When it is passed on with carbon dioxide gas, it turns the lime water milky due to the formation of a white precipitate of calcium carbonate.

The equation for the reaction of lime water and carbon dioxide follows:

$Ca(OH)_2(aq.)+CO_2(g)\rightarrow CaCO_3(s)+H_2O(l)$

Hence, the equation for this reaction is given above.
