What does iodizing mean?
Iodizing is the present participle of iodize, meaning to treat something with iodine or an iodine compound. It is most commonly associated with preparing a surface or sample for analysis and with disinfection, including the treatment of skin before certain medical procedures. The term can also refer more broadly to introducing iodine into another substance, as in iodizing seawater or incorporating iodine into salt. Iodizing is more precise than general words such as disinfecting because it identifies iodine as the active agent. In American English it is spelled with z, while British English commonly uses the form iodising. The word is chiefly technical, appearing in chemistry, medicine, biology, and environmental science, although it is also familiar from discussions of iodized salt.

Where does iodizing come from?
The word belongs to a family derived from Greek iōdēs, meaning violet, which was applied to iodine because of the colour of its vapour. Iodine was isolated and named in the early nineteenth century, and the associated verb iodize developed later in the nineteenth century. The related forms iodine, iodide, iodate, and iodic all share this etymological root.
