Salt in Toys
If you lick a toy, it will barely taste of salt. But salt is often the basic material used in the production of other materials.
The production of plastics, especially, is very difficult without salt. If you look through your toys, you will notice that many of them are made out of plastic.
But salt isn't only needed to make toys. It's also used to make many other objects you find around the home:
- soap and cleaning products
- drinking glasses and windowpanes
- plastic plates and cutlery
- shoes, bags,...
Salt (chemical formula NaCl = sodium chloride) is a chemical compound made up of sodium and chlorine gas.
Sodium is a component of soda lye, a basic chemical ingredient for many other products: soaps and other cleaning agents, paint remover, processing cotton, manufacture of aluminium and paper.
Chlorine is a light-green and very poisonous gas. It is mainly used in the production of vinyl chloride, plastics, medications and pesticides. Vinyl chloride is also essential for the manufacture of polyvinylchloride, better known as PVC, a plastic with multiple uses. You will probably recognize the smell of chlorine from indoor swimming pools, where it is used to purify the water.
Soda (sodium carbonate) was used all the way back in Ancient Egypt in order to mummify their dead. Today, it is used to manufacture glass, detergents and soap, as a bleaching agent etc. Soda water is only related to soda indirectly: a soda solution effervesces carbon dioxide when it is acidified. This carbon dioxide can be fed into water to create “soda water” (mineral water).
