What is heavy sodium carbonate?
What is heavy sodium carbonate? Sodium carbonate with the chemical formula Na2CO3 is a sodium salt that is produced by combining it with carbonic acid. CAS Number This Article is 497 19 8. The purity of this product is usually reported based on Na2O. Each kilogram of sodium carbonate contains 0.585 kilograms of Na2O.
Sodium carbonate is also known by its soda and soda ash, washing soda, soda crystals.
Sodium carbonate basically has two forms, heavy and light. The heavy form of sodium carbonate is formed after the formation of the light form. Heavy sodium carbonate is converted to sodium monohydrate (Na2CO3.H2O) by hydration of light sodium bicarbonate. Then dehydrate the water to get a higher density product and increase the size of the crystals.
The main use of heavy sodium carbonate is as a solid, especially in the manufacture of glass where it is used as a melting agent in the melting of silica (sand).
In general, the application of sodium carbonate is as follows:
The most important application of sodium carbonate is in the production of glass.
