Which is/are false about the titration using KMnO 4 solution in acidic medium ?

8 H + + MnO 4 − + 5 e − → Mn 2 + + 4 H 2 O HCl is avoided; dil. H 2 SO 4 is used. C 2 O 4 2 − → CO 2 I − → I 2 2 × 1 = x × 5 1 × 1 = y × 5

Which is/are false about the titration using KMnO₄solution in acidic medium ?

Answer:

A, B, C

Solution:

$8 H^{+} + MnO_{4}^{-} + 5 e^{-} \to Mn^{2 +} + 4 H_{2} O$

HCl is avoided; dil. $H_{2} SO_{4}$ is used.

$C_{2} O_{4}^{2 -} \to CO_{2} I^{-} \to I_{2} 2 \times 1 = x \times 5 1 \times 1 = y \times 5$
