what is the practicle advantage of using dichromate (density= 1.325g/ml) over diethylether (density= 0.713g/ml) for extracting organic compounds an aqueous solution using a separatory funnel? What is the disadvantage?
Homework Answers
The advantage is that the ether solvent which solubilizes the desired organic compound has very less boiling point, and hence it is easy to dry the organic compound.
The disadvantage is that the extraction process (mixing process) generates more pressure, and hence it may cause an explosion if not carefully done.

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...

Acid/Base Extraction Liquid-liquid extraction is a technique that can be used to physically separate two substancesthat have varying solubility properties. Typically an aqueous solution can be extracted with anorganic solvent to isolate a compound or vice-versa. The specialized piece of glassware that isemployed for these types of separations is called a separatory funnel.In this experiment a mixture of benzoic acid and naphthalene will be purified using liquid-liquidextraction, more specifically an acid-base extraction. Since both compounds are soluble inethyl acetate (an...
