1) Explain what happens when NaHCO3 is added to the organic layerby the use of chemical reaction? PLEASE EXPLAIN IN DETAILthanks
HERE IS PROCEDURE OF LAB EXP:
I completed a lab experiment to prepare t-butyl chloride fromt-butyl alcohol.
It started by with t-butyl alcohol with concentrated hydrochloricacid to separate organic layers. Then saturated NaCl is added andextraction takes place, then saturated NaHCO3 added and extractiontakes place, then water added and extraction takes place, finallysaturated NaCl added again before last extraction.
Explanation / Answer
In other words, this is the separation of a substance from amixture by preferentially dissolving that substance in a suitablesolvent. By this process a soluble compound is usually separatedfrom an insoluble compound. Solvent extraction is used in nuclearreprocessing ore processing, the production of fine organiccompounds, the processing of perfumesand other industries.
Liquid-liquid extraction is possible in non-aqueous systems: ina system consisting of a molten metal in contact with molten salt,metals can be extracted from one phase to the other. This isrelated to a mercury electrode where a metal can be reduced, themetal will often then dissolve in the mercury to form an amalgamwhich modifies its electrochemistry greatly. For example it ispossible for sodium cations to be reduced at a mercury cathode toform sodium amalgam while at an inert electrode (such as platinum)the sodium cations are not reduced. Instead water is reduced tohydrogen
