Hello Every one
It is my hope that you are all doing well. I would like to give you a short knowledge on chlorine gas . If you don't know you can get know and if you know you can gain something
Chlorine is very reactive, so it is never found as the free element in nature. It occurs mainly as sodium chloride or rock salt. It also occurs in the combined state as chlorides of sodium, potassium and magnesium.
In industry, chlorine is made by electrolysis of molten sodium chloride or brine. Brine is a concentrated solution of sodium chloride in water.
In the laboratory, chlorine is made by the oxidation of concentrated hydrochloric acid. The oxidation can be brought about by a number of oxidizing agents, for example, lead (IV) oxide, manganese (IV) oxide, trilead tetraoxide (Pb3O4) or potassium manganate (VII).
The following are the USES of CHLORINE gas ;
1. Chlorine is a bleaching agent and is also used in the manufacture of other bleaches. When chlorine is added to sodium hydroxide solution, bleach is made.
2. Chlorine is added to water supplied to homes and industries to kill disease-causing germs like bacteria. If they were not killed, these pathogens might cause diseases such as cholera and typhoid. It is also used to sterilize the water in swimming pools.
3. Chlorine is used to make some important chemicals such as hydrochloric acid, chlorofluorocarbons (CFCs), tetrachloromethane (CCl4), and chloroform (CHCl3).
4. Chlorine is a reactant in the manufacture organo-chloro compounds which are used to make pesticides, antiseptics (e.g. dettol), herbicides (weed killers) and polyvinyl chloride (PVC) which is an intermediate compound in the production of plastics.
