In the following reaction, indicate which material is being oxidized, which is being reduced, which material is the reducing agent and which reagent the oxidizing agent. Don’t forget to indicate state (s, l, g, or aq).
Potassium bromide is reacted with elemental chlorine to produce potassium chloride and elemental bromine.
KBr(aq) + Cl2(ag ------------> KCl(aq) + Br2(l)
Cl2 = 0 state
KCl Cl = -1 state
so Cl is reduced from 0 to -1
oxidizing agent =
KBr Br = -1 state
Br2 Br = 0 state
Br changes from -1 to 0
so Br is oxidized.
oxidizing agent = Cl2
reducing agent = KBr
