Extracting salt from rock salt | Lothersdale Primary School
Having established that salt dissolves in water, we set about trying to remove salt from rock salt. Using a mortar and pestle, we ground the rock salt into a course powder, added it to 50ml of warm water and stirred vigorously to speed up the dissolving process. We then poured this mixture through a funnel containing a filter paper and ...
