Question
0.1 N K2C2O4.3H2C2O4.4H2O solution reacts completely with 20 ml of 0.05 M KMnO4 solution in acidic medium. Another sample of the same solution of K2C2O4.3H2C2O4.4H2O having the same volume is titrated with 18 M NaOH solution. Then, the volume of NaOH solution (in ml) required for titration is:
