Question

Assume the following reaction is carried out in acidic medium. 
6e + Cr2O72 2 Cr3+ + 7H2O

How many H+ do we need to add to the LHS to balance the H atoms?


  1. 6

  2. 7

  3. 14

  4. 10


Solution

The correct option is C

14


Count number of Hydrogen on right hand side 7 ×2 = 14
Hence, add 14 H+ ions to the side which is deficient.
Cr2O72+6e+14H+ 2{Cr}^{3+} + 7H_2O\)
