JEE Main levelSingle correct optionDifficulty 2 of 3rx122
In acidic medium, 25mL of 0.1MHX2CX2OX4 is titrated with 0.02MKMnOX4 (reduced to MnX2+). The volume of KMnOX4 solution required at the end point is:
A125 mL
B25 mL
C1250 mL
D50 mL
Answer: D
Milliequivalents of oxalic acid =25×0.1×2=5. For KMnOX4, N=0.02×5=0.1. V=5/0.1=50mL.
