The prefix ortho is used to distinguish the acid from related phosphoric acids, called polyphosphoric acids. Orthophosphoric acid is a non-toxic acid, which, when pure, is a solid at room temperature and pressure.he 85% solution is a syrupy liquid, but still pourable. As a strong acid, it is corrosive. Because of the high percentage of phosphoric acid in this reagent, at least some of the orthophosphoric acid is condensed into polyphosphoric acids.
The phosphorus in the phosphoric acid used to make most dry phosphate fertilizers as well as a few liquids is in the orthophosphate form. If ordinary phosphoric acid is heated, water is removed and the orthophosphate ions combine to form a polyphosphate.hen ammonia is added to the phosphoric acid that has not been heated, monoammonium phosphate (11-52-0) or diammonium phosphate (18-46-0) is produced depending on the ratio of the mixture. The P present in these two fertilizers is present in the orthophosphate form.
