The company's main products are tablet alkali (sodium hydroxide) content of 99%, solid alkali, caustic soda, granulated alkali
Soda ash, scientific name is sodium carbonate, common name is soda, rock alkali, washing alkali, chemical formula Na2CO3, belongs to salt, sodium carbonate containing ten crystal water is colorless crystal, crystal water is unstable, easily weathered into white powder Na2CO3, is a strong electrolyte It has salt permeability and thermal stability, is easily soluble in water, and its aqueous solution is alkaline.
Main ingredients: pure
Appearance and properties: White powder or fine particles (anhydrous pure product), astringent.
Other physical and chemical properties:
The aqueous solution of sodium carbonate is strongly alkaline (pH = 11.6) and has a certain degree of corrosivity. It can metathesize with acids and metathesis with some calcium and barium salts. There are three types of sodium carbonate containing crystal water: Na2CO3 · H2O, Na2CO3 · 7H2O, and Na2CO3 · 10H2O.
It has strong stability, but can also decompose at high temperature to produce sodium oxide and carbon dioxide.
Long-term exposure to the air can absorb the moisture and carbon dioxide in the air, generate sodium bicarbonate, and form a hard mass.
The crystalline hydrate sodium alkaloid (Na2CO3 · 10H2O) of sodium carbonate is easily weathered in dry air.
