Aim = to separate solid liquid mixture by distillation
Material required = Burner, Tripod stand, Liebigs condenser, Conical Flask, Round bottom flask,Impure water
Producer = Take the Impure water in round bottom flask and attach the Liebigs condenser to it. Keep the conical Flask at the other end of the condenser. Heat the Impure water
...Write Observation and conclusion

Answer:
Solution :
(a) Distillation process <br> Process : The solution of copper sulphate is taken in a round bottom flask called distillation flask. A thermometer and a condenser, known as Liebig's condenser, are attached with the round bottom flask with the help of adapters. Liebig's condenser is a long glass tube enclosed in a jacket of glass Cold water is circulated through the glass jacket continuously. <br> The condenser leads to another flask called receiver to collect the liquid that gets separated from the solid during the process of distillation. The distillation flask is planced on a tripod stand and heated with the help of a Bunsen burner. <br> Observation : The solution starts boiling and water vapour obtained is passed through Liebig's condenser where it is converted to water due to condensation and collected in the receiver. Solid residue is observed in the distillation flask. <br> Conclusion : Water present in the solution is vapourised leaving behind the non-volatile solid that is copper sulphate in the distillation flask and thus constituents of the copper sulphate solution are separated. <br> (b) Filtration <br> All sorts of insoluble solids can be separated from the liquid in this process. <br> Process : A mixture of saw dust and water is taken in a beaker. A filter paper is folded in the form of a cone and fitted into a funnel by moistening it with a few drops of water. The mixture is poured gently into the filter cone and collected into another beaker. <br> Observation : The liquid collected is clear and transparent. Sawdust is found over the filter paper. <br> Conclusion : The mixture of sawdust and water is separated through filtration process. The clear liquid that is collected in the another beaker on the filter paper are known as residue. <br> <img src="
