Question

Determine the molarity of the given KMnO4 solution with the help of supplied m by 2 20% solution

Answer 1

Answer:

MnO4−+5Fe2++8H+→5Fe3++Mn2++4H2O

1 mole of KMnO4 corresponds to 5 equivalents.

The normality of KMnO4 solution is 0.1N.

Hence, the molarity of KMnO4 solution is 50.1=0.02 M.

I hope my answer is correct
