do a and b

(a) When sodium sulfite solution is added to acidified potassium permanganate solution, the purple permanganate solution turns colourless. The skeleton net ionic half-cell reactions are: MnO4Mn2+SO32SO42 Construct and balance the equation of the overall redox reaction (in acidic medium) using any method. OR (b) Balance the following redox reaction which takes place in an acid solution using the half-reaction method: NO3(2+1+Al35NH3(s)+Al(OH)4(Oe)(actatic)
