Question

Determine the molarity of the given KMnO 4 solution with the help of supplied M/10 Mohr's salt solution by titration method.​

Answer 1

Answer:

Correct option is A)

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.
