A 8 gm sample of iron are containing V% (by wt) of iron Fe2+ was prese – InterviewSolution

1.	A 8 gm sample of iron are containing V% (by wt) of iron Fe2+ was present in 1 L solution. This solution required V mL of a KMnO4 solution for oxidation of Fe2+in acidic medium. If in another titration 20 mL of same KMnO4 is required, for oxidation of 20 mL H2O2 in acidic medium. Find volume strength of H2O2
Answer» A $8 g m$ sample of iron are containing $V %$ (by wt) of iron $F e^{2 +}$ was present in $1 L$ solution. This solution required $V m L$ of a $K M n O_{4}$ solution for oxidation of $F e^{2 +}$ in acidic medium. If in another titration $20 m L$ of same $K M n O_{4}$ is required, for oxidation of $20 m L H_{2} O_{2}$ in acidic medium. Find volume strength of $H_{2} O_{2}$
