You're oxidising agent will be reduced. In the molecule MnO4-, Mn has and oxidation number of +9 and in MnO2 it is +4, therefore its oxidation number has reduced, therefore Mn is reduced, therefore it is the oxidant/oxidising agent.
Answer:Al3+ indicates an ion of aluminum having a charge of + 3. I.e., since an aluminum atom normally has 13 protons and 13 electrons, this ion has 10 electrons (-10 charge) and 13 protons (+ 13 charge) giving it a charge of + 3 (-10 + 13 = +3).
