In retrieving the compound (benzoic acid) from the aqueous phase, what is the reason for having precipitation after adding HCl in the aqueous phase?
A) Carboxylate salt is less soluble in acid, so it forms precipitate after adding HCl.
B) NaCl is formed after adding in HCl, and it is the precipitate.
C) Carboxylate salt is neutralized after adding HCl, becomes less soluble in water and precipitates out.
Homework Answers
Answer is 'C'

1. After my solubility experiment, I got these results: D-glucose and benzoic acid were dissolved in NaOH while sodium benzoate, 2-naphthol, and ethanol were not dissolved in NaOH. Are the results correspond to theoretical results? And also, what are the reasons for each solute's solubility in NaOH? (i need a justification) 2.

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...

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...

LAB DESCRIPTION: In aqueous solutions the Ni2+ cation forms a complex ion with 6 H2O ligands. The formula of this complex ion is: Ni(H2O)62+. When this complex ion is mixed with aqueous NH3 a reaction occurs where some of the H2O ligands are displaced with NH3 ligands. But how many of the H2O are displaced by NH3? In this experiment you will mix nickel(II) sulfate and aqueous ammonia to synthesize a compound containing a complex ion whose formula is Ni(H2O)6-x(NH3)x2+,...
