4.9 Oxidation-Reduction (Redox) Reactions
4.7 Types of Chemical Reactions
A student mixes an acidic solution containing
\(\text{VO}_2^+\text{(aq)}\) ions with a solution containing \(\text{SO}_3^{2-}\text{(aq)}\) ions. The balanced net ionic equation for the reaction is represented below.
\[ 2\,\text{VO}_2^+\text{(aq)} + \text{SO}_3^{2-}\text{(aq)} + 2\,\text{H}^+\text{(aq)} \rightarrow 2\,\text{VO}^{2+}\text{(aq)} + \text{SO}_4^{2-}\text{(aq)} + \text{H}_2\text{O(l)} \]
Which of the following correctly identifies the reducing agent and explains the change that occurs during the reaction?
