Consider the rxn of 2.5M dichromate:
Cr2O7 2- -------> Cr 3+ ( acidic medium)
What would be the solution Normality if the reaction goes to completion?
a. 7.5 N (ANS)
b. 2.5 N
c. 0.83 N
d. 5.0 N
e. 1.13 N

balance the eq
6 e- + 14H + Cr2O7 2- --------> 2Cr 3+ + 7H2O



I KNOW THIS QUESTION HAS BEEN ASKED 3781237 times but i dont understand why they dont multiply the M by 6 since 6 e-s were transfered.

Is Destroyer wrong?
