    Hi there

    Can you help me the following question



    The answer is Sn but I do not know why. A reducing agent is something that gets oxidised so the oxidation number has to increase. The NO3 changes from -1 to 0 so why is that not the answer. Also, what is the oxidation number of Sn because if it higher than -2, then that cannot possibly be the answer

    Thanks in advance

    Oxidation number on Sn goes from 0 to +4, so it has been oxidised, but it reduces everything else.
