Acidum phosphoricum; H3PO4, an acid obtained usually from bones or by the oxidation of phosphorus. There are several forms of phosphoric acid; the ordinary form is also called orthophosphoric acid, to distinguish it from metaphosphoric monobasic or glacial phosphoric acid, HPO3, a Vitreous solid soluble in water, and pyrophosphoric acid, 2H2O.P2O5; anhydrous phosphoric acid, P2O5, obtained by the complete combustion of phosphorus, is a light deliquescent powder soluble in water; see also acidum phosphoricum.
By Stedman, Thomas Lathrop
A solid, colourless compound; highly sapid; very soluble in water, and vitrifiable by fire. It exists in bones combined with lime. It has been employed in medicine in the form of lemonade, in passive hemorrhage, typhus, phthisis, marasmus, &c., and in injection in cases of cancer of the uterus. It does not seem preferable to other acids. An Acidum phosphoricum dilutum is officinal in the London pharmacopoeia.
