WebThe oxidation of cobalt(II) to cobalt(III) by hydrogen peroxide. If you add an excess of ammonia solution to a solution containing cobalt(II) ions, you get a complex ion formed called the hexaamminecobalt(II) ion, Co(NH 3) 6 2+. This is oxidised rapidly by hydrogen peroxide solution to the hexaamminecobalt(III) ion, Co(NH 3) 6 3+. WebExample 2: The reaction between hydrogen peroxide and manganate(VII) ions. The first example was a simple bit of chemistry which you may well have come across. The technique works just as well for more complicated (and perhaps unfamiliar) chemistry.
