An iodate is a conjugate base of iodic acid. Ammonium iodate can be obtained by neutralising a solution of iodic acid with ammonia. Sodium iodate (NaIO) is the sodium salt of iodic acid. In acidic conditions, iodic acid is formed. Concentrated nitric acid only oxidises iodine to iodic acid and doesn't affect any other halogens. Iodic acid is used as a strong acid in analytical chemistry. Studies of periodic acid, iodic acid, and their salts prompted a new line of products.
