Which statements are true for electroosmotic velocity?
I Electroosmotic velocity,u_eo,is calculated experimentally using the retention time of a neutral molecule and the length of the column from the injector to the detector.
II Electroosmotic velocity,u_eo,is the product of the electroosmotic mobility, $\mu$ _eo,and the electric field,E.
III Electroosmotic velocity,u_eo,is inversely proportional to electric field strength,E.
IV Electroosmotic velocity is equal to the electroosmotic flow.

Quizplus · Accepted Answer

Electroosmotic velocity is indeed calculated using the retention time of a neutral molecule and the length of the column (I), it is the product of electroosmotic mobility and the electric field (II), and it is equivalent to electroosmotic flow (IV). Statement III is incorrect because electroosmotic velocity is directly proportional to the electric field strength, not inversely.
