Citric acid also known as 1,2,3-Propanetricarboxylic acid, 2-hydroxy-, is the organic compound with the formula C₆H₈O₇. Citric acid is a weak organic acid which is a white crystalline powder. Its EINECS registry number is 201-069-1. With the CAS registry number 77-92-9, its IUPAC name is 2-hydroxypropane-1,2,3-tricarboxylic acid.It is stable but incompatible with bases, strong oxidizing agents, reducing agents, metal nitrates. Reactions with metal nitrates are potentially explosive. Heating to the point of decomposition causes emission of acrid smoke and fumes. Citric acid can exist either in an anhydrous (water-free) form or as a monohydrate. Citric acid is soluble in water.

Application

Citric acid is a natural preservative/conservative and is also used to add an acidic, or sour, taste to foods and soft drinks. It is used mainly as an acidifier, as a flavoring, and as a chelating agent. Citric acid can also be used in food coloring to balance the pH level of a normally basic dye.

Citric acid may be used as the main ripening agent in the first steps of making mozzarella cheese. Citric acid is used as a successful alternative to nitric acid in passivation of stainless steel. Citric acid can be used as a lower-odor stop bath as part of the process for developing photographic film.Citric acid is also used to remove fatty acids in blood vessels and to lower blood pressure. Meanwhile, it can also be used for cleaning, for example, Citric acid's ability to chelate metals makes it useful in soaps and laundry detergents and Citric acid can be used in shampoo to wash out wax and coloring from the hair.
