1、 Overview
Trade name: dense soda ash
Synonym: anhydrous sodium carbonate
Other name: soda ash
Molecular formula: na2c
Molecular weight: 105.99
CAS No.: 497-19-8
Shape: white fine granular solid
Nature: specific gravity 2.532, taste astringent. It is easily soluble in water and can form a variety of hydrates with water. Neutralize with acid. It is easy to decompose at high temperature. If exposed to the air for a long time, it will absorb water and carbon dioxide in the air, form sodium bicarbonate and form hard blocks.
2、 Purpose:
Sodium carbonate is one of the important basic chemical raw materials. It is widely used in chemical industry and other industries and people's daily life.
