A solution of hydrogen peroxide, H2O2, is titrated with potassium permanganate, KMnO4, according to the following equation: 5H2O2 + 2KMnO4 + 3H2SO4 = 5O2 + 2MnSO4 + 8H2O + K2SO4. It requires 46.0 mL of 0.145 Mol/L KMnO4 to titrate 50.0 mL of the solution of H2O2. What is the mole per liter concentration of H2O2 in the solution?

  • Chemistry -

    mols KMnO4 = M x L = ?
    Use the coefficients in the balanced equation to convert mols KMnO4 to mols H2O2.
    Then M H2O2 = mols H2O2/L H2O2 I'll be glad to check your answer.
