Redox Transformations Matrix:
$$\begin{aligned} \text{Ferrous to Ferric:} &\quad \text{Fe}^{2+} \, (\text{Green}) \longrightarrow \text{Fe}^{3+} \, (\text{Yellow}) \\ \text{Iodide to Iodine:} &\quad \text{I}^- \longrightarrow \text{I}_2 \\ \text{Oxalate to Carbon Dioxide:} &\quad \text{C}_2\text{O}_4^{2-} \longrightarrow 2\text{CO}_2 \\ \text{Hydrogen Sulfide to Sulfur:} &\quad \text{H}_2\text{S} \longrightarrow \text{S} \quad (\text{Turbidity formation}) \\ \text{Nitrite to Nitrate:} &\quad \text{NO}_2^- \longrightarrow \text{NO}_3^- \end{aligned}$$
Notation: All equations assume reaction conditions are driven by either strong acidic $$\text{KMnO}_4$$ or active orange $$\text{K}_2\text{Cr}_2\text{O}_7$$.
