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.

Making calcium hydroxide. Calcium oxide reacts with water to form calcium hydroxide, which is an alkali. Here are the equations for this reaction: calcium oxide + water â calcium hydroxide. CaO + H 2 O â Ca(OH) 2. A lot of heat is produced in the reaction, which may even cause the water to boil.Page: 1  1. 2  2. 3  3.4  4.ere are the equations for this reaction: calcium oxide + water â calcium hydroxide.
