Phosphoric acid, also known as orthophosphoric acid or phosphoric(V) acid, is a weak acid with the chemical formula H3PO4. It is normally encountered as a colorless, syrup of 85% concentration in water. The pure compound is a colorless solid.Phosphoric acid is commonly encountered in chemical laboratories as an 85% aqueous solution, which is a colourless, odourless, and non-volatile syrupy liquid. Although phosphoric acid does not meet the strict definition of a strong acid, the 85% solution can still severely irritate the skin and damage the eyes.

1,Phosphoric acid is an inorganic compound. It is colorless and transparent crystal, soluble in water, and can react with alkali to form phosphate. Phosphoric acid is acidic and can react with metals to produce hydrogen, and can react with alcohols to produce phosphate esters.

2,In biochemistry, phosphoric acid is an important component within cells and is involved in biological processes such as energy metabolism and DNA synthesis.

3,Phosphoric acid is usually produced by wet and dry processes. Wet production refers to the method of producing phosphoric acid by heating phosphate rock (apatite, phosphoric acid ore) and sulfuric acid reaction; Dry production refers to the production of phosphoric acid by roasting phosphate rock, and then wet extraction, sulfuric acid reaction and other steps.

4.Phosphoric acid is mainly used in the field of water treatment as water softener, scale cleaning agent, and as a raw material for the production of phosphorous water treatment agent. Phosphoric acid has many other uses, high purity phosphoric acid can be used to make fluoride-free feed; Used as polishing agent in electroplating industry; Used as a stain remover in the printing industry. It is used as acidifier in the process of ethylene synthesis and hydrogen peroxide purification. Used as an acidifier and flavoring agent in beverage production; Used as a desiccant in the dye industry. In the textile printing and dyeing industry, it is used as a dyeing mordant and a gloss agent for silk. Used as detergent additives in daily chemical industry, for the manufacture of safety matches; Used as a clarifying agent in the sugar industry; Used as an analytical reagent in analytical chemistry.

Phosphoric acid, also known as orthophosphate, is a common inorganic acid with the formula H3PO4 and a molecular weight of 97.995. Phosphoric acid is not easy to volatilize, not easy to decompose, almost no oxidation, with acid commonness, is a ternary weak acid, its acidity is weaker than hydrochloric acid, sulfuric acid, nitric acid, but stronger than acetic acid, boric acid, etc. Phosphoric acid is easily deliquified in the air, and heat will lose water to get pyrophosphoric acid, and then further lose water to get metaphosphate. Phosphoric acid is mainly used in pharmaceutical, food, fertilizer and other industries, including as rust inhibitor, food additive, dental and orthopaedic surgery, EDIC etchant, electrolyte, flux, dispersant, industrial etchant, fertilizer raw materials and components of household cleaning products, and can also be used as chemical reagents.

1. Phosphoric acid used for fertilizers.
2. Food grade phosphoric acid is used to acidify various foods and beverages such as cola and jam, providing a sour and spicy taste.
3. As a pH regulator in cosmetics and skincare products.
4. Food grade phosphoric acid can be used for essence, canned food, light drinks and wine making
Timely yeast nutrition source and prevention of bacterial proliferation.

1.Mainly used in phosphate industry, electroplating, polishing industry, sugar industry, compound fertilizer, etc. In the food industry, it is used as a sour agent, yeast nutrient, etc
2.Mainly used to produce chemical fertilizer, detergent, food and feed additives, flame retardant and various phosphates
3.Commonly used as analytical reagent
4.For capacity and colorimetric analysis
5.In the production of silicon planar tubes and integrated circuits, aluminum film is commonly used as electrode lead, and it is necessary to photolithograph the aluminum film and use phosphoric acid as acid cleaning etchant. It can be used with acetic acid.
6.It can be used as sour taste agent and yeast nutrient. It can be used as a sour agent for condiments, cans and cool drinks. It is used as the yeast nutrient source for brewing to prevent the multiplication of miscellaneous bacteria.
