Tannic acid is a specific form of tannin, a type of polyphenol.Its weak acidity (pK a around 6) is due to the numerous phenol groups in the structure. The chemical formula for commercial tannic acid is often given as C 76 H 52 O 46, which corresponds with decagalloyl glucose, but in fact it is a mixture of polygalloyl glucoses or polygalloyl quinic acid esters with the nuer of galloyl
