Information
Sodium carbonate (Na2CO3), also soda or washing soda, is an inorganic compound. Is a sodium salt of carbonic acid. In terms of anhydrous white powder melting at 851 ° C. In water it is readily soluble to release the heat of hydration. Crystallization at room temperature can be the most important hydrate called. crystal soda (Na2CO3 · 10H2O). Aqueous solutions are strongly alkaline soda due to hydrolytic cleavage (it is a salt of a strong base and a weak acid). Soda is synthetically produced in large quantities of sodium chloride Solvay process.
Usage
Sodium carbonate is used to raise the pH to the pools.
Raise the pH to 100 g / 10 m3 increases pH of about 0.2. It depends on the composition of the water.
The ideal value is 7.1 to 7.5
Water softener: It binds ions Ca2 + and Mg2 + for the creation of water-insoluble salts.
It is also used in the manufacture of glass, paper and detergents.
