Question

In balancing the half-reaction NO(g) NO₃^-(aq) In acidic solution,how many electrons are added,and to which side?

Quizplus · Accepted Answer

NO(g) + 3H+(aq) + 2e- → NO2+(aq) + H2O(l) (multiplied by 2) NO₃^-(aq) + 9H+(aq) + 6e- → NO2+(aq) + 4H2O(l) (multiplied by 1) Comparing the two half-reactions, we can see that 3 electrons need to be added to the left side of the second half-reaction to balance the overall reaction. Therefore, the answer is E, 3 electrons added to the right side.
