Current Question (ID: 8621)

Question:

$\text{The number of moles of MnO}_4^- \text{ required to oxidise one mole of ferrous oxalate completely in an acidic medium is-}$

Options:

1. $0.6 \text{ mole}$
2. $0.4 \text{ mole}$
3. $7.5 \text{ moles}$
4. $0.2 \text{ mole}$

Solution:

$10\text{FeC}_2\text{O}_4 + 6\text{KMnO}_4 + 24\text{H}_2\text{SO}_4 \rightarrow 3\text{K}_2\text{SO}_4 + 6\text{MnSO}_4 + 5\text{Fe}_2(\text{SO}_4)_3 + 24\text{H}_2\text{O} + 20\text{CO}_2$ $\text{So we see that 6 moles of KMnO}_4 \text{ is required to oxidize 10 moles of FeC}_2\text{O}_4$ $\text{Then, 1 mole of FeC}_2\text{O}_4 \text{ would be oxidized by } = 6/10 = 0.6$
