Calcium carbonate combines with ascorbic acid in a stoichiometric ratio of 1:2. Here's the formula: CaCO 3 (calcium carbonate) + 2C 6 H 8 O 6 (ascorbic acid) ==> C 12 H 14 CaO 12 (calcium ascorbate) + CO 2 (carbon dioxide) + H 2 O (water!) This means that for every calcium carbonate molecule, you will need two ascorbic acid molecules.
