Answer 1

Answer:

Explanation:

a evaporation- evaporation method will isolate the sodium chloride from its solution in water

b chromatography-Chromatography is a technique of separation of substances which are very close in their molecular weight but differ in their molecular sizes.

c centrifugation- meaning of centrifugation the mechanism involves taking advantage of the unequal density of the particles in the mixture.

d sublimation and filtration together- By sublimation process, ammonium chloride can be obtained as sublime from the mixture which contains sodium chloride and ammonium chloride. Then filtered.

e can use magnets or handpick - Iron pins from sand – using a magnet or by hand. Magnet will attract all the iron pins and thus will get separated from sand.

Hope this helps you
