of aqueous ferric alum solution is completely reduced with Iron to give Ferrous Ions. The volume of acidified solution required for complete reaction with ferrous Ions in the solution will be
View answer and explanation
Correct option: C
Option C (40 ml) is correct because the ferric alum solution is reduced to ferrous ions, and then KMnO4 oxidizes the ferrous ions back to ferric ions. The stoichiometry of the reaction determines the volume of KMnO4 required.
