Current Question (ID: 18905)

Question:

$\text{The correct reactions among the following are:}$ $\text{a. MnO}_4^- + \text{H}^+ + \text{Fe}^{2+} \rightarrow 2\text{Mn}^{2+} + \text{Fe}^{3+} + \text{H}_2\text{O}$ $\text{b. C}_2\text{O}_4^{2-} + \text{MnO}_4^- + \text{H}^+ \rightarrow \text{Mn}^{2+} + \text{H}_2\text{O} + \text{CO}_2$ $\text{c. SO}_2 + \text{MnO}_4^- + \text{H}^+ \rightarrow \text{Mn}^{2+} + \text{H}_2\text{O} + \text{SO}_3$

Options:

1. $\text{a and c}$
2. $\text{b and c}$
3. $\text{a and b}$
4. $\text{a, b and c}$

Solution:

$\text{The reactions a and b are correct. The c reaction is the wrong reaction.}$ $\text{The correct reaction is as follows:}$ $\text{SO}_2 + \text{MnO}_4^- + \text{H}^+ \rightarrow \text{Mn}^{2+} + \text{H}_2\text{O} + \text{SO}_4^{2-}$
