Given the equation in an acidic
medium: Cr2O72¯ +
Mn2+ --> Cr2+ +
MnO4
Choose all the statements that correctly apply:
Based on the over – all balanced equation, there will be 5 moles
of Cr2O7-2
There are 5 electrons in the oxidation half-reaction BEFORE
balancing the equation electrically
After balancing it electrically, there will be a total of 40
electrons for each of the half – reaction.
There are 8 electrons in the reduction half – reaction BEFORE
balancing the equation electrically
In the over-all balanced equation, 6 moles of H2O is
present
