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.

1 Calcium oxide, calcium hydroxide and calcium carbonate can be used to neutralise soil acidity. 2  Calcium carbonate can be used to remove acidic gases from coal-fired power station chimneys reducing harmful emissions and acid rain. We know this because the surroundings get warm. ] 2  reaction takes place. 3  This forms calcium hydroxide. 4  Calcium hydroxide is soluble in water and forms a solution known as limewater which is used to test for carbon dioxide. 5  Calcium oxide, calcium hydroxide and calcium carbonate can be used to neutralise soil acidity.
