El perxido de hidrgeno, H 2 O 2 , se puede determinar por titulacin con solucin de permanganato. Si se requirieron 80.0 mL de una solucin 0.0220 molar de MnO 4 - (aq) para titular 5.0 mL de una solucin de H 2 O 2 (aq), cul es la molaridad de la solucin de H 2 O 2 (aq)? La reaccin es: 2 MnO 4 - (aq) + 5 H 2 O 2 (aq) + 6 H+ 5O 2 (g) + 2 Mn 2+ (aq) + 8 H 2 O.
