In case of whitewashing, calcium hydroxide reacts with carbon dioxide in air to form calcium carbonate, which forms a thin layer on the walls, giving them a gloss. About 10 -20% calcium carbonate is present in and writing papers. It is used to replace kaolin in the manufacture of glossy paper.

Use the mass of sodium carbonate to predict the mass of calcium carbonate that will form in your experiment. Note: if the monohydrate is used then the molar mass is not 105.98 g/mol but 124.00 g/mol because of the added mass of one mole of water per mole of sodium carbonate.
