Chlorine.

Chlorine gas is bubbled in to water , where it disproportionates

Disproportionation is a chemical term , where molecule simultaneously oxidises and reduces. Thereby its oxidation numbers change from zero (Cl2) to Cl^- ( -1) & Cl^+ ( +1(

Chlorine gas forms the chloride ions Cl^- & Cl^+

These ions react with a water molecule to form HCl + HClO

H2O + Cl2 = HCl + HClO

HCl is hydrochloric acid which is a bactericide and HClO form the 'bleach anion (ClO^-) which is also a bactericide.

These two substances together kill germs (bactericide).

NB Only sufficient chlorine is bubbled into water , as enough to act as the bactericide. You do NOT taste these chemicals when drinking water as the concentration is very low.

NNB All water supplied by a public suppliers must do this, otherwise there would be severe illness, such as Typhoid, Cholera, Dysentery.

Chloride itself is not used to kill bacteria in public water supplies.

What is chlorine commonly used for?

It is not used directly. as it is a very poinsonous green gas. However, chlorine can be dissolved in water, where it 'disproportinates', to form hydrogen chloride and hypochlorous acid(chloric(1) acid). This is used in the water supply industry, to make sure that water is free of biological comtaminants. H2O + Cl2 = HCl + HClO
