Molecular formula Na_twoCO_threemolecular weightone hundred and five.ninenine。 Also known as soda ash. Anhydrous pure product is white powder (light) or granular material (heavy), with astringent taste. 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.

enclosure: crystal water and solubility of sodium carbonate

Anhydrous sodium carbonate(soda ash) is anhydrous, the pure product is white powder (light) or granular (heavy), and the dry sodium carbonate has semi fluidity. Exposure to the air will absorb water and carbon dioxide in the air, generate sodium bicarbonate and form hard blocks.

Sodium carbonate has a monohydrate(Na_twoCO_three?H_twoO) . heptahydrate (NA)_twoCO_three?7H_twoO) And decahydrate (NA)_twoCO_three?10H_twoO) For the three crystal forms, it is necessary to keep stirring during the dissolution process, otherwise the complex of multiple crystals (in Lake stone shape) will be formed when sinking in water, resulting in difficulty in dissolution.
