Chlorine reacts with potassium bromide to form potassium chloride and bromine. In this reaction chlorine forms chloride ions: Cl2 + 2KBr --> 2KCl + Br2. Explain, using the equation, how you know that chlorine has been reduced.
It is reduced because it gains an electron in the reaction and reduction is the gain of electrons, therefore the chlorine has been reduced.
