Posted on: February 20 2019Prepare calcium lactatropic syrup for a child of 1 year according to the specified composition do not succeed.
Answer
If we make the calculation according to the equation that 1 mol (90 g) lactic acid reacts with 1 mol of calcium carbonate (100 g) for the formation of 1 mol Ca lactate (218 g) then gives 15 g CaCO3 32.7 G Ca lactate.
Water solubility of Ca lactate = 48 g/L or 9.6 g/200 ml.
If we assume, that due to the large dose of Ca lactate, the amounts of lactic acid and CaCO3 are for 1 L then per 200 ml the amount of CaCO3 = 3 g and the amount of lactic acid 2.7 g. This gives 6.54 G Ca lactate per 200 ML, a quantity lower than the maximum solubility.
A similar syrup "the phospfolacate syrup PB V" contains 5 g of calcium lactate per 200 g syrup (= 150 ml).
An unknown remains the influence of the nature of the raspberry syrup used. One can choose this preparation between raspberry liquid extract, or raspberry aroma Fantaisie or use of raspberries syrup fantaisie or of course. One cannot exclude that all these different raw materials give the same pH to the finished product??
