Product Usage
Phosphoric acid,chemical formula H3PO4,is a common inorganic acid, is a medium strong acid. It can be obtained by dissolving phosphorus pentoxide in hot water. Orthophosphoric acid industry is obtained by treating apatite with sulfuric acid. Phosphoric acid is easily deliquescent in the air. Heating will lose water to get pyrophosphoric acid, and further lose water to get metaphosphoric acid. Phosphoric acid is mainly used in pharmaceutical, food, fertilizer and other industries, including as rust inhibitor, food additive, dental and orthopedics, EDIC corrosive, electrolyte, flux, dispersant, industrial corrosive, fertilizer raw material and component household cleaning products. It can also be used as a chemical reagent. Phosphate is a nutrient for all life forms.
