Question

how can we seperate acetone and sugar solution

Answer 1

evaporation method can be used to separate them

Answer 2

If they are mixed in water, then you could try reducing the volume by boiling, but not too long in case one or other comes out of solution. Addition of an excess of acetone to the solution should precipitate the salt, which can be filtered off. Evaporation of the acetone will yield the sugar. An alternative is to mix vigorously with toluene, which will dissolve the sugar but not the salt, and separate the layers using a separating funnel (as the toluene does not mix with water).
