Question

A conductivity cell with two electrodes (dark side) are half filled with infinitely dilute aqueous solution of a weak electrolyte. If volume is doubled by adding more water at constant temperature, the molar conductivity of the cell will - 1cm 1cm 1cm (+) (–)

(A) increase sharply
(B) remain same or can not be measured accurately
(C) decrease sharply
(D) depend upon type of electrolyte
