H3PO4 is an inorganic compound acid derived from the mineral phosphorus. It is a crystalline solid, but in its less concentrated form it is a colorless syrupy liquid. it is used to acidify foods and beverages, and serves as a starting point to produce many phosphate derivatives. It is inorganic acid which is inorganic chemical.
Food grade H3PO4 is a clear, colorless liquid that has a sour taste and a strong odor. It is a weak acid with a pH of around 2.5, which means it is less acidic than vinegar. It is soluble in water and ethanol, but not in oils.
Food grade H3PO4 is used as an acidity regulator in foods like jams, cereal bars, processed meats, cheese, etc. It is also used as an acidulant in the beverage industry to help keep a check on fungi and bacteria formation. It is used to acidify foods and drinks like numerous colas and jams. The food grade H3PO4 75%/85% is mainly used as an acid agent for seasonings, canned foods, refreshing beverages, and as a nutrient for yeast (a nutritional source for yeast during brewing, which can prevent the reproduction of miscellaneous bacteria)

Fertilizers: It is used as a key component in the production of fertilizers. It is a primary source of phosphate, which is an essential nutrient for plant growth.
Food and beverages: it is commonly used as an additive in food and beverages, such as soft drinks, to give them a tangy taste. It is also used as an acidulant in jams, jellies, and other preserves.
Water treatment: it is used to adjust the pH level of water in water treatment plants. It is also used to prevent the formation of scale and corrosion in water pipes and boilers.
Metal treatment: it is used as a rust remover and as a surface treatment for metals. It is also used in the production of metal coatings and as a cleaning agent for metal surfaces.
Pharmaceuticals: it is used as a pH regulator in the production of pharmaceuticals. It is also used as an ingredient in some medications.
Flame retardants: it is used as a flame retardant in textiles, plastics, and other materials. It helps to prevent the spread of fire by releasing water and carbon dioxide when exposed to heat.
