CHEMICALS FROM SALT
Hydrogen is used in the manufacture of ammonia and margarine. Chlorine is used to sterilize water, and in the manufacture of hydrochloric acid, PVC and CFCs. Sodium hydroxide is used in the manufacture of soap, paper and ceramics.

• Salt as a raw material
• The chlor-alkali industry
• Uses of hydrogen, chlorine and sodium hydroxide

Salt as a raw material
Common salt is sodium chloride, NaCl. It can be made in the laboratory by the reaction of sodium with chlorine. However, it is found naturally in large amounts in underground deposits and sea water. It is mined from the underground deposits or obtained by evaporating the water from sea water.

Uses of sodium chloride

• Salt is widely used in the food industry as a preservative and flavour enhancer. While too much salt taken in with food is bad for us, a certain amount of salt is vital for human health. In fact you can die from lack of salt!
• Salt is used to treat icy roads in the winter. It lowers the melting point of the ice on the roads so that it melts, even when the temperature is below 0°C.
• Sodium chloride is the raw material for the manufacture of hydrogen, chlorine and sodium hydroxide by electrolysis. This is an important industrial process because these substances have many uses

Electrolysis (passing an electrical current through a solution of salt in water) produces:
Uses of hydrogen, chlorine and sodium hydroxide

You need to be able to describe some of the many uses of the products of the electrolysis of brine: hydrogen, chlorine and sodium hydroxide. All three products are useful individually, but can also be combined together to make two important new products. Sodium hydroxide and chlorine can be made into sodium chlorate (I) (sodium hypochlorite); which is sold as a solution. Sodium chlorate (I) is a strong oxidising agent, and is excellent for killing bacteria, but highly explosive. It is used in the production of sodium hypochlorite (common name - bleach), used in the home.  Hydrogen and chlorine react together to form hydrogen chloride. This is made into hydrochloric acid by dissolving it in water. Hydrochloric acid made in this way is very pure, and can be used safely in the food and pharmaceutical industries. 
NaCl is absolutely essential to life on earth. And sodium chloride has literally thousands of uses! One of that chlorine. It plays a key role in the manufacture of thousands of products we depend on every day, including volleyballs, computers, cars, pool chemicals, medicines and cosmetics.
Those are just a small sampling of the many items that are made using chlorine.
