Road salt is not purified even a little bit, it even contains small
stones... the label says Not for human consumption. Water softener
salt is only partially purified, the stones are eliminated, also
labled Not for human consumption. Actually pure salt does have an
odor, when dissolved in distilled water it has a slight odor of the
sea.
