Seperaion Scheme for extraction lab

Disolve 1 g of a mixture containing biphenyl and benzoic acid in 15 mL diethyl ether. Add to seperatory funnel. Then add 20 mL of sodium bicarbonate to the seperatory funnel. After extractiing 3 times add HCl to aqeuous flask until acidity is roughly 3. Let it cool then use vaccum filtration. and collect crystals after they dry in oven. For organic flask add sodium sulfate as drying agent then decant to obtain dry ether filtrate. Cover and take to NEVAP. Then collect the crystals. I just need help with the seperation scheme
