4.9 Oxidation-Reduction (Redox) Reactions
A student investigates a treatment process for chromium-containing rinse water. The solution is acidified, and chromium(VI), present as \(\text{Cr}_2\text{O}_7^{2-}\text{(aq)}\), is reduced to \(\text{Cr}^{3+}\text{(aq)}\).
Which equation represents the correctly balanced reduction half-reaction for \(\text{Cr}_2\text{O}_7^{2-}\text{(aq)}\) in acidic aqueous solution?
