An aq. solution of $0.5 M KMn O_{4}$ is divided into two parts. One part of it requires $125 m L$ of $1.5$ M aq. solution of oxalate ions m acidic medium, while another part requires 270 mL of 0.5 M aq. solution of iodide ions m neutral medium which converted into $I_{2}$ only. Calculate total volume: of the initial ${KMnO}_{4}$ solution

Detailed Solution

Let $V_{1}$ and $V_{2}$ are volumes of ${KMnO}_{4}$ in 1st part and 2nd part

Reaction (a) ${KMnO}_{4} + C_{2} O_{4}^{2 -} \overset{Neutral}{⟶} {CO}_{2} + {Mn}^{2 +}$

$\Rightarrow 0.5 \times V_{1} \times 5 = 1.5 \times 125 \times 2 \Rightarrow V_{1} = 150 mL$

Reaction (b) ${KMnO}_{4} + I^{-} \overset{Neutral}{⟶} I_{2} + {MnO}_{2}$

$\Rightarrow 0.5 \times V_{2} \times 3 = 0.5 \times 270 \times 1 \Rightarrow V_{2} = 90 mL$

so, initial volume $= 150 + 90 = 240 mL$
