    So I'm going through a dumb phase right now and can't figure out the oxidation numbers for this reaction:

    Cu + 2AgNO3 -> Cu(NO3)2 + 2Ag

    I know Cu has an oxidation number of 0 in the reactant and Ag has an oxidation number of 0 in the product. So what are the oxidation numbers of AgNO3 and Cu(NO3)2 and how did you get to it?? Thaaaankssss

    The oxidation of Ag is (+1) because NO3 is (-1) and there is no overall charge on AgNO3 therefore the charges cancel out. For Cu(NO3)2, the NO3 is (-1) but you have 2 of them so Cu would have to be (+2) to cancel the charges. Hope that helps
