Oxidation-Reduction Reactions (Section 4.4)
The following reactions (note that the arrows are pointing only one direction) can be used to prepare an activity series for the halogens:
\(\mathrm{Br}_{2}(a q)+2\ \mathrm{NaI}(a q) & \longrightarrow 2\ \mathrm{NaBr}(a q)+\mathrm{I}_{2}(a q)\)
\(\mathrm{Cl}_{2}(a q)+2\ \mathrm{NaBr}(a q) & \longrightarrow 2\ \mathrm{NaCl}(a q)+\mathrm{Br}_{2}(a q)\)
(a) Which elemental halogen would you predict is the most stable, upon mixing with other halides? (b) Predict whether a reaction will occur when elemental chlorine and potassium iodide are mixed. (c) Predict whether a reaction will occur when elemental bromine and lithium chloride are mixed.
