What+is+Chlorine?

You usually think of chlorine as in swimming pools. You probably know the taste. Chlorine is used to keep pools clean and sanitary. (Yes, I know you sometimes drink pool water.) But, it is actually a natural gas. It has a yellowish-green color. In short form it is known as Cl2. The temperature is room temperature. That means if the room that it is in is 63 degrees, the chlorine will be about 63 degrees. Its uses are for bleaching, used in pools to keep them clean, for cleaning industrial waste and sewage, and added to tap water to make it clean. There are many more uses of chlorine. But you have to be careful. If you inhale too much, you can die. It is also a respiratory irritant. But don`t worry, you`ll be fine if you just drink a little pool water :). Chlorine was discovered in 1714, and about 100 years later was named. We have been using chlorine to clean our pools for about 100 years. And in 1915, chlorine was used as a war gas. Don`t worry about chlorine. It is just here to help us.
