Solution of slaked lime produced by the reaction 1.13 is used for whitewashingwalls. Calcium hydroxide reacts slowly with the carbon dioxide in air to form a thinlayer of calcium carbonate on the walls. Calcium carbonate is formed after two tothree days of whitewashing and gives a shiny finish to the walls. It is interesting to notethat the chemical formula for marble is also CaCO3-Ca(OH),(aq) + CO2(g) CaCO3(s) + H2O(1)(1.14)(Calcium(Calciumhydroxide)carbonate)
