A solution of hydrogen peroxide, H2O2 , is titrated with potassium permanganate, KMnO4 , according to the following equation:

5 H2O2 + 2 KMnO4+ 3H2SO4 -> 5O2 + 2 MnSO4 +8H2O + K2SO4

It requires 46.9mL of 0.145 mol/L KMnO4 to titrate 50.0 mL of the solution of H2O2 .

What is the moles per litre concentration of H2O2 in the solution?

    Determine mols KMnO4.
    mols KMnO4 = M x L = ??

    Convert mols KMnO4 to mols H2O2 using the coefficients in the equation.
    mols H2O2 = mols KMnO4 x (5 mol H2O2/2 mol KMnO4) = ??

    Convert mols H2O2 to mols/L.
    M = mols/L
