The following reactions (note that the arrows are pointing
only one direction) can be used to prepare an activity series
for the halogens:
Br2(aq) + 2 NaI(aq) → 2 NaBr(aq) + I2(aq)
Cl2(aq) + 2 NaBr(aq) → 2 NaCl(aq) + Br2(aq)
Predict whether a reaction will occur when elemental chlorine and potassium iodide are mixed.
