Answer. In general, the techniques of dissowing, filteleation and evapouection are used. The mixture of the two solids is added to water. The soluble solid is allowed to dissolve and the insoluble could is filtered out. Whereas A mixture of benoic acid and ensophenone can be separated by using a base. Ince base alld becomes souble and other becomes insoluble. Benzoic auld and benzophenone mixture when treated neitt Na₂CO3 colution, benzoic acid becomes souble and other can be separated easily.
