How naphthalene and potassium sulphate mixture separated from each other?

Naphthalene and potassium sulfate can be separated through a process called recrystallization. Since naphthalene is soluble in organic solvents like ethanol or acetone but potassium sulfate is soluble in water, one can dissolve the mixture in a suitable solvent. Afterward, the solution can be filtered to remove the insoluble potassium sulfate, and naphthalene can be recovered by evaporating the solvent. Alternatively, differences in melting points could also be exploited, as naphthalene has a melting point of about 80°C, while potassium sulfate remains solid at that temperature.
