Chemical appearance: The 85% phosphoric acid is an aqueous solution that is colourless, odourless and not volatile. It presents in the form of a syrup, thick but still pourable. The basic conjugate base of this acid is a dihydrogen phosphate anion which is a mix of hydrogen and phosphate ions. 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.
