Chemical application and strengths:

  • There are two types of phosphoric acids, food grade and industrial grade phosphoric acids. The food grade phosphoric acid is added to foods and drinks to give them a slight acidic feel. It is common in colas and jams where it gives them a sour or tangy taste.

  • The food grade type is also used as nutrition agent for food containing yeast. This helps in the growth of yield in the production process without the formation of other bacteria that are not essential in the maturing of foods or drinks. In sugar production, the acid acts as reaction catalyst.

  • The industrial-grade phosphoric acid is used as a drying agent, a catalyst and cleaners. It is also used in the production of various chemical treatment liquids, phosphates and electrolyte treatment liquids. In the metal production industry, phosphoric acid is used as a coating to prevent rust in metals. In addition, the acid is used in the semiconductor industry in the making of liquid crystal display films, electronic chips as well as cleaning of such products.

  • Although phosphoric acid is generally referred to as a weak acid. It has all the characteristics of an acid. According to PubChem, it is also a sequestering agent that binds to various divalent metal cations including iron and magnesium. This quality allows it to be used in a number of electrolyte correction applications in both the food and industrial applications
