Over time, hydrogen peroxide, H2O2, degrades into water and oxygen gas. A bottle of hydrogen peroxide is expired and you need to determine the concentration. A titration is performed using the following equation: 3 H2O2(aq) + 2 NaMnO4(aq) → 3 O2(g) + 2 MnO2(aq) + 2 NaOH(aq) + 2 H2O(l) Note that permanganate ion, MnO4-, is purple, while manganese (IV) ion, Mn4+, is colorless. A quantity of 683 mL of 3.44 M NaMnO4 was measured and placed in a beaker. The solution...

The concentration of hydrogen peroxide in a solution is determined by titration with a 0.1258 M Ce++ solution. The balanced net ionic equation for the reaction is: 2ce4+ (aq) + H2O2(aq) + 2H20(1)— 2Ce3+ (aq) + O2(g) + 2H30+ (aq) (a) If 18.37 mL of the 0.1258 M Ce4+ solution are needed to react completely with 40.00 mL of the hydrogen peroxide solution, what is the concentration of the hydrogen peroxide solution? M (b) Which of the two solutions was...
