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+. WebOct 8, 2024 · In both reactions $\ce{H2O2}$ is oxidized by the more powerfull oxidizers permanganate ($\ce{KMnO4-}$) and dichromate ($\ce{Cr2O7^2-}$). Whether or not oxygen is produced depends on the actual reaction and not necessarily on pH. A rule is that when hydrogen peroxide is oxidized by a stronger oxidant, free oxygen is produced.
