Iodides

Iodides are the salts of Hydriodie Acid (q.v.), i.e. are hydriodie acid in which the hydrogen has been replaced by a metal, or equivalent group of elements. Of these the most important is potassium iodide, which is very largely employed for chemical and other purposes, while many iodides are used to a great extent in medicine and photography. Other compounds of iodine with elements other than metals are also termed iodides, as, e.g., iodide of phosphorus, etc.
