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 pKa of this is between 6.8-7.20. This compound can be made when phosphoric acid reacts with a sodium salt like sodium halide. Sodium phosphate dibasic. This compound is also known as disodium phosphate and has the molecular formula of Na 2 HPO 4. The molar mass of the compound is 142 g mol -1. When two sodium cations replace the hydrogen atoms in the phosphoric acid, sodium phosphate dibasic is obtained. So in the laboratory we can make this compound by reacting two equivalents of sodium hydroxide with one equivalent of phosphoric acid.
