RATEOFDECOMPOSITIONOFHYDROGENPEROXIDE - Lab Report ExampleTherefore, hydrogen bleach appears to exhibit a metastable characteristic in settlement or its pure evince (Egan and Nills, 2005). Oxygen evolution is rapid at room temperature and in concentrated solutions the released heat may increase the temperature so that an explosion occurs. On heating, hydrogen peroxide decomposes and it may be explosive. The stability of hydrogen peroxide at room temperature is attributed to the fact that the first step in its thermolysis involves the splitting of the molecule into hydroxide radicals whose institution demands much heat. Catalysts such as silver, gold, platinum, manganese dioxide act as heterogeneous catalysts whereas ions such as I-, IO-, OH-,Fe3+ or copper act as homogenous catalysts.catalysis of hydrogen peroxide decomposition by iron ions is an important in redox catalysis. The steps in the process as demonstrated by Evgenil, Oleg and Gerts (2005), gives information on the mec hanisms of redox catalysis. This decomposition is also important in processes in living organisms. The decomposition may be represented as below25 mL of the tenvolume hydrogen peroxide was dilute to about 200 ml with distilled water. A Dewar flask was rinsed with distilled water and then with a some mL of the dilute H2O2 solution. Hydrogen peroxide solution was added into the Dewar flask, and the solution temperature noted at a constant value. 10 ml of Fe3+(a) catalyst solution was added into the beaker spell stirring gently. A stop watch was used to keep track of time.Thirty seconds after the addition of the catalyst, 10 mL aliquot of the reaction solution was pipetted and transferred into an Erlenmeyer flask containing 18 mL of 2 M H2SO4. The acid provides an acid medium for the titration and also quenches the decomposition reaction. 10 mL samples were draw from the reaction pastiche at 5 min intervals and titrated with potassium permanganate. The titration reaction follows the
