Background: Extraction lab using diethyl ether as solvent. Mixed an unknown mixture of benzophenone and salicyclic acid. Try to separate the 2. 2 Questions: 1 In separation of ether sol'n from NaOH layer, some of the sol'n was left behind in the ether solution, how would that change the benzophenone recovery? Also indicate the top and bottom layer. 2 Suggest reasons for low benzophenone recovery . My Attempt: 1. I think benzophenone dissolves in water while the diethyl ether dissolves the acid. If I am right, the diethyl ether should be at the bottom? As for the recovery, it would decrease since you would be leaving behind benzophenone in the ether sol 2. ??? I have no idea except for it evaporating but there should definitely be something important here since everyone got low recovery. THANK YOU!
