Phosphoric acid can be made by dissolving phosphorus(V) oxide in water. This makes a very pure phosphoric acid that is good for food. A less pure form is made by reacting sulfuric acid with phosphate rock. This can be purified to make food-grade phosphoric acid if needed.

Phosphoric acid is produced by the treatment of calcium phosphate rock with sulfuric acid. The resultant liquid is then filtered for the removal of calcium sulfate.

Abstract. When phosphate rock is leached with hydrochloric acid, radium can be removed by co-precipitation with Ba 0.4 Ca 0.6 SO 4 and uranium by extraction with a 5% solution of tributyl phosphate in hexane or Varsol. Phosphoric acid is then separated from calcium chloride solution and other impurities by extraction with undiluted tributyl phosphate.

Salts of phosphoric acid are called phosphates. Preparation. Phosphoric acid can be made by dissolving phosphorus(V) oxide in water. This makes a very pure phosphoric acid that is good for food. A less pure form is made by reacting sulfuric acid with phosphate rock. This can be purified to make food-grade phosphoric acid if needed.

Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock which contains high amounts of phosphate minerals.The phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% to 20% phosphorus pentoxide (P 2 O 5).Marketed phosphate rock is enriched ("beneficiated") to at least 28%, often more than 30% P 2 O 5.This occurs through washing, screening ...

The present paper deals with the treatment of phosphate obtained from a commercial sample of Akashat phosphate ore in hydrochloric acid. The factors studied are effects of the temperature of dissolution, acid concentration, and the time required for

Hydrochloric acid or muriatic acid is a colorless inorganic chemical system with the formula H 2 O:HCl.Hydrochloric acid has a distinctive pungent smell. It is classified as strongly acidic and can attack the skin over a wide composition range, since the hydrogen chloride completely dissociates in aqueous solution.. Hydrochloric acid is the simplest chlorine-based acid system containing water.

The production of white phosphorus was improved by using phosphate rock and sulfuric acid instead of bone ash and hydrochloric acid; and by the use of reverberatory furnaces instead of the direct-heated furnaces. White and amorphous phosphorus remained the main product of Albright and Wilson …

Phosphoric acid (also known as orthophosphoric acid or phosphoric(V) acid) is a weak acid with the chemical formula H 3 P O 4. Orthophosphoric acid refers to phosphoric acid, which is the IUPAC name for this compound. The prefix ortho-is used to distinguish the acid from related phosphoric acids, called polyphosphoric acids.

Consumption of phosphoric acid for its acid properties is relatively small (e.g., treatment of metal surfaces, beverage acidulation). Phosphoric acid is the leading intermediate product or processing step between phosphate rock and the end markets for phosphorus in phosphate form. The supply/demand balance for phosphoric acid is supply driven.

Phosphoric acid is not a particularly strong acid as indicated by its first dissociation constant. It is a stronger acid than acetic acid, but weaker than sulfuric acid and hydrochloric acid. Each successive dissociation step occurs with decreasing ease. Thus, the ion H. 2. PO. 4 ‾ is a very weak acid, and HPO. 4 2 ‾ is an extremely weak acid.

Both batch and bench-scale continuous tests were made. Western phosphate rock concentrates were acidulated with hcl, and the digestion liquors were processed by solvent extraction. Phosphoric acid was extracted with isoamyl alcohol and recovered from the organic extract by contact with an nh4f solution.
