39. Which of the following statements concerning microelectrode is INCORRECT?
(A) Microelectrodes can provide high sensitivity because they have a large double-layer capacitance at the electrode-solution interface.
(B) Microelectrodes have at least one dimension in the micrometer range, resulting in enhanced mass transport by radial diffusion.
(C) Microelectrodes are well suited for fast cyclic voltammetry.
(D) Microelectrodes allow electrochemical measurements in solutions with high resistance and minimal supporting electrolyte.
(E) Microelectrodes exhibit reduced charging currents compared with conventional electrodes.
