A mixture of benzoic acid and naphthalene was separated by a liquid-liquid extraction by converting the benzoic acid into its water soluble sodium salt. How can the benzoic acid be recovered after the two layers were separated? Group of answer choices Acidify the aqueous solution containing the sodium benzoate to pH 2 and filter. Add an excess of 1.0 M NaOH to the aqueous solution containing the sodium benzoate and filter. Add diethyl ether to the aqueous solution containing the sodium benzoate and filter. Dry the the aqueous solution containing the sodium benzoate with anhydrous sodium sulfate and filter.
