4. To titrate 25.00 mL of a solution of hydrogen peroxide (H2O2), in acidic buffer medium (pH= 1.00), a volume of 19.38 mL of a standard potassium permanganate solution was used 0.05000 mol/L. a) Write the half-equations and the overall chemical equation that translates the titration reaction. b) Calculate the concentration of hydrogen peroxide in the analyzed solution. c) Sketch the titration curve, indicating what is represented on each axis. d) Calculate the potential of an inert electrode in the titrant, after the addition of 25.00 mL of standard solution of KMnO4. Data: E (O2(g)/H2O2(aq)) = 0,68 V; E (MnO4 - (aq)/Mn2+(aq)) = 1,51 V
