Q5: Benzoic acid in a solution with toluene is to be extraction using pure water as solvent in a counter current multistage extraction unit. The benzoic acid concentration in the toluene feed is 20% and the weight ratio of water to toluene is 1.45. If 95% of the benzoic acid is to be remove in the water phase. Calculate the number of stages required if the equilibrium relationship: a) Y-1.5X b) y-1.5x

A chemist wants to determine the Ksp of BaC2O4 at T = 285.15 K. He prepared 0.10 L of saturated solution by putting the solid in distilled water maintained at the given T. The solution was filtered, in which a 0.01 L aliquot of the filtrate was drawn. The chemist finds that 0.0107 L of 5.60 x 10-4 M hydrochloric acid was used to reach the endpoint. If 2 mol HCl reacts with 1 mol of dissolved oxalate during the titration, How much dissolved oxalate (in M) was in the titration flask?
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.
