Tannic acid, also known as tannic acid, is an organic compound with the chemical formula C76H52O46. It is a yellow or brownish powder. Its aqueous solution turns blue-black when it meets iron salt solution. Adding sodium sulfite can delay the discoloration. In industry, tannic acid is widely used in tanning leather and making blue inks. Tanning acid solidifies proteins. People chemically treat pig skins and raw cowhide with tannic acid, which can solidify the soluble proteins in the hides. As a result, the rawhide, which would stink and rot after a few days, turned into beautiful, clean, flexible and durable leather. This tanning process is called leather tanning.
