      How much electricity is required in Coulomb for the oxidation of (i) 1 mole of to?                               (ii) 1 mole ofto?        (iii) 1 mole of  to 

    Answer:

      Coulombs = nF = Q n = electrons, F = 96500 (i) Thus Q = 1 x 96500 C = 96500 C                 [1] (iii) Thus Q =5x96500= 482500 C                    [1]
