Propose a method to separate a mixture containing phenol, benzoic acid, naphthalene, and p-nitro aniline. Phenol is soluble in sodium hydroxide solution but insoluble in neutral water or sodium bicarbonate solution. Benzoic acid is soluble in either sodium hydroxide or sodium bicarbonate solutions. Write out the structures of the molecules in your scheme.

Naphthalene is mostly insoluble in water. How would you recrystalize benzoic acid contaminated with naphthalene?

Draw a flow diagram for the separation of benzoic acid, phenol, and naphthalene. Enough detail must be included for someone to perform the experiment, however, you do not need to include masses or volumes ( this question pertains to acid/base extractions, ect. ) Please be neat, as I seek guidance and mastery, thank you.

Experiment: Extraction to seperate benzoic acid and naphthalene. Procedure- Place 2 g of a 1:1 (by weight) mixture of benzoic acid and naphthalene in a small beaker; record the exact mass of the mixture in your notebook. Add 35 mL of dichloromethane to the beaker and stir until the solid mixture has completely dissolved. Carefully pour the solution into a separatory funnel. Add 20 mL of 3.0 M NaOH to the separatory funnel, stopper it, and shake the mixture with...

I have an unknown mixture of Benzoic acid, Dimethyl Terephthalate, and Naphthalene dissolved in Dichloromethane. I need to separate the mixture to find the composition using some sort of acid base reation and a distillation. How would I do that? I think that I could use steam distillation to remove the naphthalne but im not really sure on that. Any help would be apprectiated. I start with 25mL of the unknown mixture.

A protein retained on an affinity chromatography column is usually eluted off the column by (circle the correct answer) A. increasing the salt concentration in the buffer B. changing the temperature of the elution buffer. C. allowing the retained protein to naturally come off the column after the non-specifically bound proteins have first passed through the resin. D. adding the protein's free ligand.
