Mixtures of amino acids can be analyzed by separating the mixture into its components through ion-exchange chromatography. amino acids placed on a cation-exchange resin containing sulfonate (−so−3) groups flow down the column at different rates because of two factors that influence their movement: ionic attraction between the sulfonate groups on the column and positively charged functional groups on the amino acids, and hydrophobic interactions between amino acid side chains and the strongly hydrophobic backbone of the polystyrene resin. for each pair of amino acids listed, determine the order of elution from a cation exchanger in ph 7.0 buffer.

Achemistry student weighs out 0.306 g of citric acid (h3c6h5o7), a triprotic acid, into a 250 ml volumetric flask and dilutes to the mark with distilled water. he plans to titrate the acid with 0.1000 m naoh solution. calculate the volume of naoh solution the student will need to add to reach the final equivalence point. be sure your answer has the correct number of significant digits.
