4.9 Oxidation-Reduction (Redox) Reactions
4.7 Types of Chemical Reactions
A student analyzes a vanadium-containing battery-recycling solution by reacting the vanadium species with permanganate in acidic solution. The net ionic equation for the reaction is
\[ \text{MnO}_4^-\text{(aq)}+5\text{VO}^{2+}\text{(aq)}+\text{H}_2\text{O(l)}\rightarrow \text{Mn}^{2+}\text{(aq)}+5\text{VO}_2^+\text{(aq)}+2\text{H}^+\text{(aq)} \]
Which choice correctly identifies the reducing agent and the oxidation-state change of its transition-metal atom?
