Q76 / 180 · NEET 2014 · Chemistry

When 0.1 mol MnO42- is oxidized the quantity of electricity required to completely MnO42- to MnO4- is

  • A
    96500 C
  • B
    2×96500 C
  • Correct answer
    C
    9650 C
  • D
    96.50 C

Solution

MnO42-→MnO4-
0.1  mole
v.f.=1
So, 0.1 mole=96500×0.1
=9650 C charge is required

Hence, the correct answer is option: 'C'.
