Which of the following solution will exactly oxidize 25 ml of an acid solution of 0.1 molar iron oxalatea 25 ml of 0.1M KMnO4b 15 ml of 0.1 M KMnO4​

Answer»

Answer:

First we have to find the n-factor of the equation of KMNO4 and ferrous oxalte the which is Fe(C2O4) which are 5 and 3 respectively.

THUS, now by using the formulae of M1V1 = M2V2.

We GET that M1= 0.1*5.

And, V2 = 25ml, M2= 0.1*3.

Then on solving we get, 0.5V1 = 7.5.

Hence, V1 will be 15ml. Thus, we get to know that 15ml of 0.1M KMNO4 will OXIDIZE 25ml of an acidic solution.
