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?

Sagot :

pyromorphite
5H2O2 + 2KMnO4+ 3H2SO4 = 5O2 + 2MnSO4 + 8H2O + K2SO4

0,145 moles of KMnO4----------in--------1000ml
x moles of KMnO4---------------in------------46ml
x = 0,00667 moles of KMnO4

according to the reaction:
2 moles of KMnO4------------------5 moles of H2O2
0,00667 moles of KMnO4----------------x
x = 0,01668 moles of H2O2

0,01668 moles of H2O2---------in-----------50ml
x moles of H2O2--------------------in----------1000ml
x = 0,334 mol/L H2O2
