how to get %recovery? here recovered benzoic acid is 0.14 g.
Part 1 - ExtracHon of an Acidic Organic Compound 1. Secure a small, clean separatory funnel to a ring stand with a clamp. 2. Label three small flask (25 or 50 mL) with one of the following: "benzoic acid", "ethyl-4- aminobenzoate" and "organic layer". 3. Obtain exactly 10.0 mL of a solution containing benzoic acid and ethyl-4-aminobenzonate in ethyl acetate. 4. Extract the solution containing the two compounds with...

5) A 100.0 mL aqueous solution containing 2.50 g of compound Z results is extracted with 25.0 mL of ethyl acetate. The ethyl acetate is evaporated to yield 0.95 g of compound Z. 4 points Calculate the partition coefficient (also known as the distribution coefficient) K, for compound Z in ethyl acetate and water, where K = (concentration of Z in diethyl ether) + (concentration of Z in water): Calculations Answer

1. What experimental difficulty would you encounter if you had neglected to include a drying step before evaporating the ether solution of the neutral organic compound? 1b. An extraction procedure specifies that an aqueous solution containing dissolved organic material be extracted twice with 10-mL portions of diethyl ether. A student removes the lower layer after the first extraction and adds the second 10-mL portion of ether to the upper layer remaining in the separatory funnel. After shaking the funnel, the...

Acid/Base Extraction Liquid-liquid extraction is a technique that can be used to physically separate two substancesthat have varying solubility properties. Typically an aqueous solution can be extracted with anorganic solvent to isolate a compound or vice-versa. The specialized piece of glassware that isemployed for these types of separations is called a separatory funnel.In this experiment a mixture of benzoic acid and naphthalene will be purified using liquid-liquidextraction, more specifically an acid-base extraction. Since both compounds are soluble inethyl acetate (an...
