Homework Answers
If the aqueous phase was basic ( not acidified ) than acidic compound(carboxylic acid) will ionize by deprotonation and prefer the basic aqueous phase.
But here, in the question you are using acidified aqueous phase , so carboxylic compound will not ionize by deprotonation and prefer organic phase.
Hence, correct option is : "3- the acidic compound will be nautral ( non- ionized) and end up in the organic phase."

An extraction was performed using mixture of the compounds below. First the organic mixture was dissolved in dichloromethane, treated with acid, and separated. The organic layer was then treated with base and separated. Sort the compounds based which layer it was in at the end of the extraction Acidic Aqueous Layer Basic Aqueous Layer Organic Layer Only

An experiment performed using solid to liquid extraction, liquid-liquid extraction, heating, and recrystallization to isolate caffeine, was not totally successful due to their being very little to no product of caffeine left when the time came to recrystallize the pure caffeine. During the experiment what could of caused there to be not enough caffeine to recrystallize it? ethyl acetate was used as the organic solvent hexane and acetone was used to recrystallize the crude caffeine, through mixture and boiling. Could...

In the acid/base extraction lab, a carboxylic acid was separated
from fluorene by extracting the carboxylic acid into the aqueous
layer using NaOH solution (a review of this experiment before lab
will be helpful). Phenols (aromatic alcohols) can also be separated
using this method. In a mixture of a phenol and a non-reacting
organic compound, the phenol may be selectively removed from an
organic solvent by extracting with a dilute NaOH solution. After
separating the organic and aqueous layers, the...

In my liquid-liquid extraction experiment, I have to explain where the "rest" of my product is. we were given 1.000 gram to start with of one acid and one neutral compound and separated using the liquid liquid extraction. First we added NaOH into the flask and shook it and observe the separation of the two layers. Then I drained them into separate beakers and added HCL to the aqueous layer containing the acidic component and I evaporated the solvent off...
