Question

Uses of salt and chemical reaction

Answer 1

The many uses of Salt

Most people probably think of salt as simply a white granular food seasoning. In
fact, only 6% of all salt manufactured goes into food. Apparently we use salt in more than 14,000 different ways from the making of products as varied as plastic, paper, glass, polyester, rubber and fertilisers to household bleach, soaps, detergents and dyes.

Everyone uses salt, directly or indirectly.

Water Conditioning

Water is considered hard when it contains calcium & magnesium (hardness ions). Replacing them with 'soft' sodium ions softens the water avoiding scale build-up on hot water appliances.

Industrial Chemicals

The greatest single use for salt is as a feedstock for the production of industrial chemicals and in total accounts for 68% of all the salt manufactured.

Food Grade Salt

All animals, humans included, require both sodium and chloride for life and health. Since the body cannot manufacture either, it is important these 'essential' nutrients form part of our daily diet.

Highway Deicing

Salt is the most effective, readily available, and economical highway deicer in use today and accounts for 8% of all salt productio.

Paper Manufacturing

In paper making salt is used to manufacture caustic soda and chlorine. Caustic soda is used to process wood fibres and chlorine is used to bleach the pulp.

Agriculture

Livestock, poultry and other animals need salt supplements as part of a nutritionally balanced diet to remain healthy and disease free.
