Did you know?
Witrynacompound.The pK, values of the acidic compounds viz., benzoic acid and 2 naphthol are 4.17 and 9.51 respectively. Benzoic acid is a stronger acid while 2-naphthol is weakly acidic.Seperation of this mixture will require the extraction of the acidic components one by one. You will be using the technique of solvent extraction for WitrynaFigure 2. Basic Extraction of an Organic Acid At this point, you can separate the organic ether layer and the aqueous layer. The aqueous layer can then be acidified and …

Witrynalike a weak base to draw out the strong benzoic acid. This bicarbonate will have no effect on the weak naphthol. The weaker acid, naphthol (pKa ~10) will only be removed with a strong base such as NaOH. If the NaOH was added first, it would extract both the naphthol and the benzoic into a solution from the naphthalene and diether. WitrynaThe flow chart below outlines a general procedure for separating acidic, basic and neutral organic compounds using the principles of the solubility switch. Organizer NW Organi ARCH 21 Pag In this experiment, you will separate a mixture that contains an acid (benzoic acid) and a neutral compound (naphthalene) only. Benzoic acid …
