Tannic acid is an organic compound with a chemical formula of C76H52O46. It is yellow or brownish-yellow powder. When its aqueous solution meets iron salt solution, it turns blue-black. Adding sodium sulfite can delay the discoloration. In industry, tannic acid is widely used in tanning leather and making blue ink. Tannic acid coagulates proteins. People chemically treat raw pigskin and raw cowhide with tannic acid, which can coagulate the soluble protein in the raw hide. As a result, the raw hide, which would have rotted and rotted after a few days, turned into beautiful, clean, flexible, and durable leather.
