please provide an equation for the reaction of the aqueous layer with Hdl.
The following experiment was done:
add 1g of 1:1 mixture of benzoic acid and naphthalene. add 30 ml of
dichloromethane to dissolve. Add solution to a separatory funnel.
Add 15ml of NaOH, shake and separate the two layers.
with the aqueous layer, containing NaOH, combine 6M HCl until you have reached a pH of 2. ice to speed up the production of crystals.

Draw the reaction mechanism with chemical structures in the separation of naphthalene and benzoic acid by extraction. 1g of Naphthalene/benzoic acid mixture is dissolved in 15 mL dichloromethane, transferred to a separatory funnel where 10 mL 2.5M NaOH(aq) is added. Organic and Aqueous layers are separated, and 12M HCl(aq) is added to the aqueous layer while cooling, forming a precipitate, which is vacuum filtrated. Don't understand how to draw each chemical structure!

Experiment: A mixture of equal proportions of benzoic acid, ethyl 4-aminobenzoate, and 1,4-dimethoxybenzene are to be separated by extraction using the solvent diethyl ether. Day 1: Part A. Isolation of the basic component: In a small beaker, dissolve 3 g of the mixture (benzoic acid, ethyl 4-aminobenzoate, and 1,4-dimethoxybenzene) in 30 mL of diethyl ether and transfer the mixture to a 125- mL separatory funnel (see Fig. 1) using a little diethyl ether to complete the transfer. Add 10 mL...

Extraction of solids: Experiment outlined below
Draw a “roadmap” of the experiment, containing chemical
structures and “layers” (organic and aqueous). This should contain
the individual reactions occurring in each step, and show which
layer the various components are present. Make sure you think about
whether the acetaminophen, caffeine and aspirin are neutral,
protonated or deprotonated.

Experimental procedure Weigh approximately 2.5 gof benzoic acid contaminated withtable salt (NaCl) as precisely as possible (record the exact quantity). Transfer the solid to a 100 mL separatory funnel and add 30 mL of ethyl acetate. In a 50 mL beaker, add 20 mL of water and 1.0 mL of 3 M hydrochloric acid. Transferthe mixtureto the separatory funnel. The solid...

How can the NMP oxalate salt be converted back to NMP? Here is the procedure: PROCEDURES Part A: Synthesis of (±)-N,N-dimethyl-3-phenyl-3-(4-trifluoromethylphenoxy)propanamine To the 250-mL round-bottom flask (RBF) containing (±)-3-(dimethylamino)-1-phenylpropanol (product from Lab 6) and a magnetic stir bar, add 4 mL of 4-chlorobenzotrifluoride and 30 mL of dimethylacetamide (DMA). With stirring, add to this mixture 30 mL of 1.0 M potassium tert-butoxide (caustic alkali!) in tert-butyl alcohol using a syringe. Using a simple distillation apparatus, distill the mixture slowly, with...
