With sat-urated salt solutions the salt content remains constant if there is enough undissolved salt at the bottom of the container (= saturated solu-tion). With unsaturated salt solutions this is not the case (only liquid is visible) and a defined rel-ative humidity above such solutions cannot be guaranteed.
