Since hydrogen peroxide decomposes into oxygen gas and water [9], the solution of H₂O₂ was standardized with 0.0932 M potassium permanganate. 10.00 mL of Hydrogen Peroxide (Unknown Concentration), 10.00 mL of 0.1000 M sulfuric acid, and 10.00 mL of distilled water were added to a beaker. A burette was first rinsed with distilled water and potassium permanganate, then filled with the standardized 0.0932 M KMnO₄. The acidified hydrogen peroxide solution was then titrated with the potassium permanganate and the concentration of hydrogen peroxide was determined to be 0.0960 M. This was then diluted to a final concentration of 0.0300 M H₂O₂.
