Type the correct answer in the box. jay, kip, and tia are each measuring the concentration of a solution. they are doing experiments separately. they are all are using a colorimeter—a device used for measuring colors. jay repeats the experiment five times and takes the average measurement, while kip performs the experiment once. tia repeats the experiment three times but chooses one of the measurements instead of the average. the measurements taken by are least likely to contain random errors.

You mix the pks of succinic acid are 4.21 and 5.64. how many gramsa graduate student at sdsu wants to measure the activity of a particular enzyme at ph 4.0. to buffer her reaction, she will use a buffer system based on one of the acids listed below, which acid is most appropriate for the experiment? of monosodium succinate (fw = 140 g/mol) and disodium succinate (fw = 162 g/mol) must be added to 1 l of water to produce a solution with a ph 5.28 and a total solute concentration of 100 mm? (assume the total volume remains 1 liter, answer in grams monosodium succinate, grams disodium succinate, respectively.) volumes of 0.05 m nah2po4 and 0.05 m na2hpo4 (pk's for phosphoric acid are 2.15, 6.82 and 12.38). which of the following best describes the resulting solution?
