(10 pts) a) Predict whether fumarate or maleate will have a greater electrophoretic
mobility. Briefly explain your answer and give a quantitative estimate of their relative
mobilities.
(10 pts) A solution in a capillary has an electroosmotic mobility of 1.3 imes 10-8(m^(2))/(V).s at pH
At pH 12 the electroosmotic mobility is 8.1 imes 10-8(m^(2))/(V).s. If 27kV is applied across the
62-cm long capillary:
a. How long will it take a neutral solute to travel 52cm from the injector to the detector
at pH2 ?
b. Same as in " a ", but at pH12 ?
