    I think this might be missed in the last video:
    Scandium and Zinc are d block elements but they are not transition metals

    miss shouldn't it be triaquatrihydroxoiron (III) complex since the oxidation number is 3? Why do we put 2 in the brackets?

      And why is it iron and not ferrate?

    Hello, Miss. In the second last reaction of Fe (II) with NH3, if the NH3 is present in excess, the Fe complex can have a ligand exchange, right?
    Also, I really appreciate your efforts in the making of these fantastic videos

      Hi. For the complexes of the transition metal ions "Mn2+", "Fe2+" and "Fe3+" there will be no reaction with excess NH3 or OH-. Therefore, when excess NH3 is added Fe (II) complex [Fe(H2O)4(OH)2], ligand exchange does not take place. In fact, the complex of Mn2+, Fe2+ and Fe3+ are the only complexes on which "excess" NH3 will not cause ligand exchange.

      @@TahaAk6 Ahhh, got it. That was a great explanation, thanksss! :D
