Iodotannic acid is a chemical compound that is commonly used as a mordant in the dyeing of textiles. The word is spelled phonetically as /aɪəʊdəʊtænɪk ˈæsɪd/. The first syllable "iodo-" denotes the presence of an iodine atom in the compound, while the second syllable "-tan-" refers to the tannic acid component. The final syllable "-ic" indicates that the compound is an acid. Proper spelling of chemical words is crucial in research and laboratory work, where precision and clarity are of utmost importance.

The word "iodotannic acid" is derived from two main components: "iodo-" and "tannic acid".
1. "Iodo-": The prefix "iodo-" is derived from the element iodine (symbol I on the periodic table). It refers to the presence of iodine in the compound.
2. "Tannic acid": Tannic acid is an organic compound found in plants, particularly in bark and fruits. It is a type of polyphenol, specifically a gallotannin derivative. The term "tannic acid" derives from its initial isolation from oak bark, known as "tannin". Over time, the more specific term "tannic acid" came to be used for the purified form of tannin.
So, the term "iodotannic acid" indicates the presence of iodine in a compound with the properties of tannic acid.
