12. Identify the oxidizing agent in the following reaction:
8H+ (aq) + 6Cl- (aq) + Sn (s) + 4NO3- (aq) SnCl62- (aq) + 4NO2 (g) + 4H2O (l)
What are we supposed to look for? Oxidizing agent...doesn't that just mean its getting reduced. Can we just pick the one that has lost an oxygen. In this case, NO3- would be the oxidizing agent because it becomes NO2?
What if the question asked what is the reducing agent?
