how many moles are there of the reducing agent. What is the molarity of the reducing agent? Oxidizing agent --> KMnO4 Reducing Agent --> Fe +2 Volume of Fe +2 = 25 mL Concentration of KMnO4 = 0.1290 M Volume of KMnO4 added to titration = 35.02 mL Reaction is 5 Fe(+2) + MnO4(-) + 8 H(+)--> 5 Fe(+3) + Mn (+2) + 4 H20
