A mixture contains

{Na}_2 {C}_2 {O}_4

and

{KHC}_2 {O}_4

in 1:1 molar ratio. Mixture is neutralised by

100 \mathrm{~mL}

0.01 \, \mathrm{M} \, {KOH}

. What volume of

0.01 \, \mathrm{M} \, {KMnO}_4?

Thus, the same mixture is oxidised by

View answer and explanation

Correct option: D

80 \mathrm{~mL}

Option D (

80 \mathrm{~mL}

) is correct because it is calculated by finding the millimoles of

{C}_2 {O}_4^{2-}

and equating it to the milliequivalents of

KMnO_4
