It is a tricarboxylic acid with the chemical formula C6H8O7 and is commonly used as a food additive, preservative, and flavoring agent. Citric acid is also used in the pharmaceutical industry, as a chelating agent in cleaning and personal care products, and in the production of cosmetics and detergents. It is a white crystalline powder with a sour taste and is soluble in water.


Citric acid is a weak organic acid which has the appearance of colourless, odourless crystals with a strong acid taste. The chemical is denser than water. It exists in two forms, anhydrous and monohydrate forms.
1. The anhydrous form- this form has no water of crystallization and is also known as the water-free form of citric acid.
2. Monohydrate form- this form has a water molecule that is associated with one citric acid molecule. It is formed when citric acid is crystallized from cold water. It can be converted to the anhydrous form at about 780C.
