I think I'd better clear this one up a bit....
Iodine (as iodide) _is_ added to salt because people need it -
particularly if they live far from the sea and never get any fish. There
were lots of problems with this in some areas. Sodium chloride itself
is not hygroscopic, but one of the common impurities is. Yet another
item is added to the salt to stop the clogging problems.
