Phosphoric acid (CAS 7664-38-2) is an inorganic acid with the chemical formula H3PO4. It is a colorless, transparent, and viscous liquid at room temperature, with a sharp acidic taste.
Phosphoric acid is widely used in various industries. In the food industry, it serves as an acidulant, flavor enhancer, and yeast nutrient. It is also used in the manufacture of phosphate salts, as a polishing agent in the electroplating industry, and as a degreasing agent in the printing industry. Additionally, it is used in the production of detergents, as a component in fertilizers, and in the purification process of ethanol and hydrogen peroxide.
The production of phosphoric acid typically involves the reaction of phosphate rock with sulfuric acid, although other methods such as the use of nitric acid or other processes are also employed. The reaction yields a mixture of phosphoric acid and calcium sulfate, from which the acid can be separated and purified.
It is important to handle phosphoric acid with care due to its corrosive nature. Concentrated solutions can cause skin irritation and burns. Adequate safety measures, including the use of personal protective equipment and proper ventilation, should be taken when working with phosphoric acid
