Phosphoric acid has a wide range of applications in industry and serves as a crucial raw material for producing fertilizers, detergents, food additives, and other products. Additionally, phosphoric acid plays a key role in nature and within living organisms, particularly in cellular energy conversion (such as the generation and utilization of ATP) and bone formation. Moreover, the buffering properties of phosphates make them indispensable in laboratory research and pharmaceutical preparation, widely used to maintain pH stability in solutions. This characteristic provides essential support for scientific research and medical applications.
