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
Do NOT use it, its a very poisonous gas (Toxic gas used in World War I)
chlorine is commonly used for pool water to get rid of germs
Chlorine is involved in a lot of cleaning processes because it is poisonous to most living organisms. Chlorine bleach can be used for a thorough cleanup, and is most commonly found in public pools to kill all the bacteria that has the potential of growing. There is also a certain amount in drinking water for the same cleansing reasons.
Chlorine is not found in its elemental form as chlorine gas, being a halogen, is highly reactive. The most common compound of chlorine is sodium chloride or common salt. This can be found dissolved in sea water.
Chlorine is an element, Cl on the Periodic Table. So, What does chlorine mean? It is the proper name of the element, Chlorine. It is often used for sanitizing water, as it kills small microbes (harmful and otherwise). With respect to Swimming Pools, it comes in various forms: Tablet Chlorine (Usually Trichlor) Liquid Shock (Sodium Hypochlorite: Chlorine gas suspended in salt water) and Granular shock (can be either Calcium Hypochlorite, or Sodium Dichlor, most commonly)
Sodium chloride is salt. It is used to season food and it is used to melt ice on icy roads. I'm sure it has many other uses.

It is most commonly used in keeping pools clean.
Chlorine.
Germany. They used Chlorine gas in the second battle of Ypres.
No, it is made out of salt
Pools ;)
Chlorine is most commonly found in salt, "sodium chloride." Potassium chloride (KCl, aka sylvite) is another common chlorine containing mineral. Chlorine may be extracted from these salts and used to treat municipal water supplies to prevent cholera and other water born illnesses. Chlorine may also be placed in man made swimming pools to inhibit bacterial growth.
It is used to disinfect drinking water in municipal water systems.
Two examples are: sodium hypochlorite and chloramine.
i would say chlorine as it is used commonly in organic compounds, CFC's, salts (NaCl) and as a disinfectant in swimming pools.
The most commonly used disinfectant that you can use on a camping trip is iodine that comes in the form of small tablets.
