Could acetone be used instead of diethyl ether to dissolve an unknown mixture and perform the microscale separation via liquid/liquid extraction of your basic,acidic, and neutral components? Explain your answer.
Homework Answers
the solubility of given solvent for an extraction depands on several of its properities,when compared to di ethyl ether, aceton is high volatile and higher boing point. dielectric constant, polarity and polarizability influence strongly the solvent-solvent and solute-solvent interactions. Another important chemical properity of a solvent is its basicity. compounds having functional groups containing electronagative atoms aceton is higher electonagativity these influence the sepsration.
In the unknown sample nature to extracted with aceton may be inert or active with respect to the compound to extracted, aceton may be inert or active with respect to to the unknown compound to be extracted,in the unknown components in compond interact with aceton frist basic componets are separated, next to be neutral components, then followed by acidic components of the un known compounds. becouse acetone is acidic nature.

An unknown mixture (dissolved in diethyl ether) contains only 2 of the following : benzoic acid, phenol, aniline and napthalene. You use the acid-base extraction method and want to identify the 2 compounds in your original mixture. 1) To separate the organic acid you add NaOH and to separate the organic base you add HCl.In both cases these extractions are followed by extractions with water. Why do we add water? Why is this step important? (A clear explanation please). 2)When...

From You have a mixture of benzoic acid, hexamethylenediamine, and 1-octanol dissolved in diethyl ether. You wish (for some reason) to separate these compounds and have pure samples of each. Devise a liquid-liquid extraction protocol that would allow you to do this. (up to 20 points) Your answer should be clear and concise.

The goal of this experiment is to separate a mixture of two unknown compounds into individual Components and to identify the compounds. Answer the questions below. More than one answer may be possible. Why do we need to be especially careful when working with diethyl ether? Fumes can cause drowsiness & dizziness, and in high concentration, loss of consciousness Because it is highly acidic and can burn the skin Because it is extremely volatile and flammable. Of all of the...

Your answer must employ the following reagents: methylene chloride, hydrochloric acid (1M & 6M), sodium hydroxide (1M & 6M), 10% sodium bicarbonate (aq). Clearly indicate the product(s) and layers formed following each step of your separation scheme. IMPORTANT: p-cresol is soluble in sodium hydroxide solution but insoluble in neutral water or sodium bicarbonate solution. 2-ethylbenzoic acid is soluble in both sodium hydroxide and sodium bicarbonate solutions.
