The mixture of phenol and benzoic acid is separated by adding $NaHCO_{3}$ to produce brisk effervescence with sodium benzoate .

When benzoic acid react with $NaHCO_{3}$ then sodium benzoate is produced which is soluble in water and separated from non aqueous solvent . Organic compounds are soluble in organic solvent and inorganic compound mainly soluble in inorganic solvent like water.

What is brisk effervescence?

Brisk effervescence is when continuous gas evolution occurs in a chemical reaction like CO2. When HCl is added in $NaHCO_{3}$ then CO2 evolved.
