The best method for the separation of naphthalene and benzoic acid from their mixture is

Classify matter according to physical state.

Draw a diagram showing the setup of the apparatus for the process. Draw a diagram of a bubble plate type fractionating column. When do we require such a type of column for separating two liquids? Explain the principle involved in the separation of components of a mixture of liquids by using a fractionating column. What industrial applications does this process have?
