Question: (a) A particular solution in a particular capillary has an electroosmotic mobility of 1.3 10-8 m2/(V s) at pH2 and 8.1 10-8 m2/(V

(a) A particular solution in a particular capillary has an electroosmotic mobility of 1.3 × 10-8 m2/(V s) at pH2 and 8.1 × 10-8 m2/(V s) at pH 12. How long will it take a neutral solute to travel 52 cm from the injector to the detector if 27 kV is applied across the 62-cm-long capillary tube at pH 2? At pH 12?
(b) An analyte anion has an electrophoretic mobility of - 1.6 ×10-8 m2/(V s). How long will it take to reach the detector at pH 2? At pH 12?
