Increasing the fluid intake of a human subject so that the urinary calcium fell from 120 mg/l to 25 mg/l, for example, resulted in the pHn increasing from 6.48 to 8.22. The 2% citric and formic acid solubilities of phosphate rock residues extracted from partially acidulated materials (20 and 35% acidulation) manufactured from two phosphate rocks (both ground and unground) in the presence of monocalcium phosphate, monosodium phosphate, calcium chloride, calcium sulphate, calcium carbonate, sodium carbonate and aluminium and iron sulphates have been examined. Render date: 2021-01-12T01:06:57.697Z That's the problem with the salts of weak acids. This would indicate that some deactivation of the phosphate rock had taken place during acidulation, the degree of which was dependent on the acidulation level and could be more readily observed in changes in 2% formic acid solubility than in 2% citric acid figures. Generally one uses 2% citric acid. (Yes, we may consider phosphoric acid weak, if we are talking of its third proton.) Specifically tetracalcium phosphate, hydroxyapatite, and (alpha- and beta-) tri-calcium phosphate.

The experimental data show that pHn can be elevated by decreasing the calcium, magnesium and phosphate concentrations. Calcium carbonate or calcium phosphate are even more insoluble, yet even they will not precipitate in similar conditions (i.e., in acidic media).
