PREPARATION OF BORIC ACID Principle Borax or Sodium tetraborate on reaction with acids, such as Hydrochloric acid or Sulphuric acid gives insoluble boric acid. It precipitates as a white precipitate. It is collected, washed, free from acid, dried and weighed. In the laboratory, boric acid is obtained by adding a mixture of concentrated H2SO4 and water (1:5) to a boiling solution of borax (60g in 160ml of water) the solution is filtered and kept aside for crystallisation. The crystals of boric acid are separated and then washed until they become free from sulphate ions. Finally dried at Room temperature. Uses Boric acid is widely used as an antiseptic for the treatment of minor cuts and burns. Furthermore, this compound is also used in medical dressings and salves. Very dilute solutions of boric acid can be used as an eyewash. Owing to its antibacterial properties, boric acid can also be used for the treatment of acne in humans. In its powdered form, it can also be sprinkled into socks and shoes to prevent athlete’s foot (tinea pedis). Procedure 1. Dissolve 15 g of Borax in 25 ml of distilled water. 2. Boil the solution. 3. Add Dilute sulphuric acid to the boiled solution (10%v/v) little by little with constant stirring. 4. Hot liquid is filtered and kept aside for crystallization 5. Boric acid is filtered, washed with water to remove soluble sulphate. 6. Dry boric acid at room temeperature and weigh. Reference - Practical Pharmaceutical Inorganic chemistry by Dr. G.
