What is the molarity of a KMnO4 solution standardized against 1.356 gram Na2C2O4 (134 g/mole) requiring 25.1 mL of the solution in acidic medium.
Solution:
The given word problem is about oxidation reduction reaction or redox in short. There's a change of their oxidation numbers in the redox reaction and sulfuric acid is used as a catalyst as follows
Therefore, from the chemical reaction above, the molarity of KMnO4 solution is
