A 0.1097 gm sample of $As_{2} O_{3}$ required 26.10 ml of $KMnO_{4}$ solution for its titration. The molarity of $KMnO_{4}$ solution is

Answer:

Solution:

Let, molarity of $KMnO_{4}$ solution be M

∴ Eq. of $As_{2} O_{3} =$ Eq. of $KMnO_{4}$ solution

$\frac{0.1097}{198} \times 4 = \frac{26.10 \times M \times 5}{1000} ($ Equivalent weight $As_{2} O_{3} = \frac{198}{4})$

Molarity $= 0.017 M \approx 0.018$
