Product Introduction
Soda ash, scientific name of sodium carbonate, also known as soda, ash, an important chemical basic raw materials, soda industry's main products. Usually white powder, easy to decompose at high temperature, soluble in water, aqueous solution is alkaline. Sodium carbonate and water to generate Na2CO3 · 10H2O, Na2CO3 · 7H2O, Na2CO3 · H2O three hydrates, of which Na2CO3 · H2O is the most stable, and the dissolution heat dissolved in water is very small, mostly used in the photographic industry, commodity name carbon oxygen. Na2CO3 · 10H2O, also known as crystal alkali or washing alkali, dissolved in water is an endothermic process, easy to weathering in the air. Na2CO3 · 7H2O is unstable and can be precipitated from saturated sodium carbonate solution only in the range of 32.5~36 ℃.
