dissolve the salt &amp; filter out the chalk

2)Common Salt from its impure sample

use a solvent, then evaporate off the solvent

3)Common salt from sea water

evaporate the water off

4)Cream from Milk

centrifuge

5)Gases of the Air

cool them to condense them , then warm them up slowly &amp; evaporate off one at a time (distil)

6)oil and water

use a sepatory funnel

7)ammonium chloride and common salt

heat the mix &amp; NH4Cl will evap off as NH3 &amp; HCl ,

8)kersone and petrol

distill
