40. Kulonometric titration of the alikvolate fraction of the analyzed potassium permanganate solution with a volume of V (KMN04) was carried out by electro -generated iron (II) in a sulfuric environment with direct current I in the presence of an indicator of ferroin. As an auxiliary reagent, iron salt (III) was used. The current was passed over time τ before changing the color of the solution.
Write the equations of reactions occurring during the titration process on the generator electrode and in the solution. According to the given data below, calculate the molar concentration of the equivalent of C (L/Z KMN04) and the molar concentration C (KMNO4) potassium permanganate in the analyzed solution.
