24. Which statements regarding polargraphy are FALSE?
(A) The dropping-mercury electrode yields a more reproducible current-potential behavior
than other electrodes.
(B) The reduction of a metal into a mercury amalgam is more favorable than reduction to
the solid state. (C) The current we seek to measure is the charging current, and the current that interferes
with every measurement is the faradaic current.
(D) In sampled current polarography, the current is measured only in the initial
milliseconds of the life of each Hg drop.
(E) For quantitative analysis, the limiting current should be controlled by the rate at which
analyte can diffuse to the electrode, so an unstirred solution is used to minimize
convection.
