Audited Supplier Product Properties
Phosphoric acid, also known as orthophosphoric acid, is a common inorganic acid, a medium-strong acid with a chemical formula of H3PO4 and a molecular weight of 97.994. It is not easily volatile, not easily decomposed, and has almost no oxidizing properties. It has the general property of acid and is a ternary weak acid. Its acidity is weaker than that of hydrochloric acid, sulfuric acid and nitric acid, but stronger than that of acetic acid and boric acid. Phosphoric acid is easily deliquescent in the air. Heating will lose water to obtain pyrophosphoric acid, and then further lose water to obtain metaphosphoric acid. Phosphoric acid is mainly used in pharmaceutical, food, fertilizer and other industries, including as a rust inhibitor, food additive, dental and orthopedic surgery, EDIC corrosive agent, electrolyte, flux, dispersant, industrial corrosive agent, fertilizer, raw material and component of household cleaning products, also Can be used as a chemical reagent.
Phosphoric acid 85% is one of the food additives, used in food as a sour agent and a yeast nutrient. Phosphate is also an important food additive and can be used as a nutritional enhancer.
