Isolation and Identification of a Solid Product

Add syrupy phosphoric acid to a little of your product and heat with diphenylamine. Heat carefully and observe any colour changes. 

Run an infrared spectrum of your product and compare it with that of reagent manganese (II) oxalate dihydrate. 

Submit a sample of your product to elemental analysis and obtain a mass spectrum. 

9 Kinetics of the Mn02 catalysed decomposition of aqueous H2O2 

Although the decomposition of hydrogen peroxide to water and oxygen, is thermodynamically feasible, its solution can be kept without decomposition at low temperature and in absence of catalysts. One of the efficient catalysts is manganese dioxide. The kinetics of the catalysed decomposition can be studied by following die volume of oxygen liberated.
