1. What is phosphoric acid?
Phosphoric acid, with other synonyms of acide phosphorique, Orthophosphoric acid, etc., is one kind of clear liquid. The chemical formula of phosphoric acid is H3PO4 and the molecular weight of phosphoric acid is 97.99. Phosphoric acid is soluble in water and ethanol, and when comes to its storage, it should be kept sealed in the cool, dry and well-ventilated place, away from incompatible substances and corrosives materials. And the chemical structure of phosphoric acid is as below.
2. Physicochemical properties of phosphoric acid
1). Density of phosphoric acid: 1.885 g/mL (liquid)/1.685 g/mL (85% solution)/2.030 g/mL
(crystal at 25 °C)
2). Melting point: ~40 °C
3). Boiling point: 158 °C at 760 mmHg
4). Water solubility: MISCIBLE
5). Phosphoric acid solubility in water: 5.48 g/mL
6). Molar refraction: 13.52
7). Molar mass of phosphoric acid: 97.994 g/mol
8). Viscosity of phosphoric acid: 2.4–9.4 cP (85% aq. soln.) 147 cP (100%)
3. Phosphoric acid reactions
One common industrial synthesis methods of phosphoric acid is wet process, and the chemical equation for phosphoric acid is Ca5(PO4)3X + 5 H2SO4 + 10 H2O → 3 H3PO4 + 5 CaSO4·2H2O + HX. (where X may include OH, F, Cl, and Br). If you want to know more about the synthesis method, you could refer to the phosphoric acid manufacturer for more technical details, like Yunnan Chengjiang U-best Industrial Co., Ltd. This phosphoric acid producer is specialized in the research, develop, manufacturing and distribution of chemical products including rock phosphate, phosphorus chemical industry, chemical raw materials and other phosphorus products, and it is especially experienced in production of phosphoric acid.
