5) No.
Sodium bicarbonate is basic and does not form any H bonds (as H bond donor) with diethyl ether any more than pure water. Thus ether is not more soluble in bicarbonate.
In general bicarbonate is used to wash off the acidic impurities in ether layer.

Extraction of benzoic acid and 9-fluorenone using diethyl ether. (please do not include ethyl 4- aminobenzoate). I have to create a flow chart to diagram the key steps of the experiment and isolation of products. 0.100g of benzoic acid and 9-fluorenone are dissolved in diethyl ether. The extraction solvent is 5% sodium hydroxide (to extract the acidic component from the organic phase). Saturated sodium chloride is added to the organic layer. drying the organic solution: anhydrous sodium sulfate is added...

Write the balanced chemical equation for the reaction between sodium bicarbonate and sulfuric acid (products are sodium sulfate, carbon dioxide, and water). If you used 10 mL of 2.0 M H2SO4 and 2.50 g of NaHCO3 in a similar reaction to what you did in lab, which reactant is limiting? Show all calculations.

Okay, so we had solid benzoic acid, ethyl 4- aminobenzoate, and 9-fluorenone all dissolved in diethyl ether (4ml). We separated the basic component by adding 3M HCl, we separated the acidic component by adding 3M NaOH. I don't understand what happens here. To isolate the acidic solution, we added 6 M NaOH and used the vacuum to recover the solid. To isolate the basic solution we added 6M HCl. Here are the questions I am having trouble with... • Why...
