Phosphoric acid (orthophosphoric acid, monophosphoric acid or phosphoric(V) acid) is a colorless, odorless phosphorus-containing solid, and inorganic compound with the chemical formula H 3 P O 4. It is commonly encountered as an 85% aqueous solution , which is a colourless, odourless, and non- volatile syrupy liquid.
Phosphoric acids and phosphates. Appearance. Pyrophosphoric acid. In chemistry, a phosphoric acid, in the general sense, is a phosphorus oxoacid in which each phosphorus (P) atom is in the oxidation state +5, and is bonded to four oxygen (O) atoms, one of them through a double bond, arranged as the corners of a tetrahedron.
Example of phosphoric acid production. Wet process phosphoric acid is prepared by adding sulfuric acid (H 2 SO 4) to apatite or tricalcium phosphate rock resulting in the following reaction: 3 H 2 SO 4 + Ca 3 (PO 4) 2 + 6 H 2 O ↔ 2 H 3 PO 4 + 3 CaSO 4 •2H 2 O Wet-process acid has to be purified by removing fluorine and other undesirable ...
Triammonium phosphate can be prepared in the laboratory by treating 85% phosphoric acid with 30% ammonia solution: [citation needed] H 3 PO 4 + 3 NH 3 → (NH 4) 3 PO 4 (NH 4) 3 PO 4 is a colorless, crystalline solid. The solid, which has the odor of ammonia, is readily soluble in water. The salt converts to diammonium hydrogen phosphate (NH 4 ...
Infobox references. Tricalcium phosphate (sometimes abbreviated TCP), more commonly known as Calcium phosphate, is a calcium salt of phosphoric acid with the chemical formula Ca 3 (PO 4) 2. It is also known as tribasic calcium phosphate and bone phosphate of lime (BPL). It is a white solid of low solubility.
1968 ― The shop for the production of phosphoric acid and Ammophos. 1970 ― second shop for the production of granulated super phosphate. 1972 ― The start of production of extruded mixtures of phosphorus-potassium fertilizer combination in the shop (before 1990.) 1973 ― In December, the fourth line for production of sulfuric acid.
