4. state your observations upon addition of the hydrogen peroxide solution to the mixture at this point. write two half reactions, one for the h2o2 and one for the cobalt complex and the net redox reaction that occurs between these two reagents at this point in the synthesis showing products formed. a side reaction should have been observed at this point also, namely a strong effervescence of the solution upon the peroxide addition. was this observed? in addition to acting as an oxidizing agent the h2o2 can be catalytically decomposed by the metal ion. write a reaction for that process and identify the gas apparently released at this point from the solution.
