How can a mixture of sodium sulfate (soluble in water) and barrium sulfate (insoluble in water) be seperated?

Question

so you mean filter it?

Answer 1

Put all of them in a beaker that contains water. Stir it and the sodium sulfate will dissolve in the water and the barrium sulfate will remain. Then pour the mixture & use a glass funnel and put a piece filter paper on top of the funnel to collect the barrium sulfate while you are pouring.

Answer 2

BaSO4  is the least soluble sulfate, and any salt containing Na is water soluble (usually) so just rinse with distilled water you can filter them on the filter paper remains BaSO4 and in the filtrate NaSO4 But it is better to use a centrifuge machine first it will separate them better you will obtain a residue of BaSo4 and centrifugate (liquid) of NaSO4 now you can filter ....

Additional info BaSO4 is only soluble in boiling conc H2SO4 (concentrated boiling sulfuric acid) it is very stable and insoluble in all mineral acids and alkali

Answer 3

Sodium sulfate - soluble in water

Barrium sulfate - insoluble in water

  They are already separated, you just drain off the sodium    sulfate to separate.
