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...
