Problem- In building a flow chart for the extraction of a mixture of 1:1 of the follwoing two compounds:1,1'Biphenyl, and cinnamic acid, and diethyl ether, aqueous NAHCO3, aqueous NAOH and queous HCL. What would the sodium bicarbonate be used for? Based off of the experiment we did in class I would disolve the biphenyl and cinnamic acid in diethyl ether, add NAOH to react with the cinnamic acid, then separate the two layers that would appear. One would be the diethyl ether with biphenyl and the other would be sodium cinnamate. Then for the Sodium Cinnamate you would add HCl to convert it back to cinnamic Acid. In class we used a vacuum to dry the acidic crystals. I just don't know what to do with Aqueous NaHCO3.
