Lime water is a solution of calcium hydroxide (slaked lime). When carbon dioxide is bubbled through it, a solid precipitate of calcium carbonate is formed. Calcium carbonate is chalk or limestone, and it is this that makes the lime water cloudy. calcium hydroxide + carbon dioxide calcium carbonate + water.hen carbon dioxide is bubbled through it, a solid precipitate of calcium carbonate is formed. Calcium carbonate is chalk or limestone, and it is this that makes the lime water cloudy. calcium hydroxide + carbon dioxide calcium carbonate + water.
to test for carbon dioxide is already dissolved in limewater, after this shake up the test tube, is it be that carbon dioxide is present then 2 things will happen: 1) the limewater will turn cloudy as CO2 is a precipatate is this solution.his is because the lime water reacts with the carbon dioxide to cause the precipitation of calcium carbonate-CaCO3 as shown below: Ca(OH)2 (aq) + CO2 (g) = CaCO3 (s) + H2O (l) Please see the related link for more information.
