Soda ash, scientific name sodium carbonate, chemical Na2CO3, molecular weight 105.99, also known as baking soda or alkali ash.

Soda ash belongs to salt, not alkali, and is an important chemical raw material. The appearance is white powder or fine-grained crystals, with a bitter taste, soluble in water, and its aqueous solution is alkaline. It can undergo neutralization reaction with acid to generate corresponding salts. Soda ash has strong hygroscopicity and can easily absorb moisture from the air, gradually turning into sodium bicarbonate. Therefore, it is important to seal and store it in a dry and ventilated environment before and after use to avoid moisture absorption and clumping, which can affect the effectiveness of use.

Soda ash has a wide range of applications, and can be divided into industrial grade soda ash and food grade soda ash according to different uses. It can also be divided into heavy soda ash and light soda ash according to different packing densities. According to the different sulfides, they are divided into ordinary alkali and low salinity alkali.

Industrial soda ash is one of the important chemical raw materials used in the production of chemicals, cleaning agents, detergents, and also in photography. In industrial soda ash, it is mainly used in light industry, building materials, and chemical industry; Next are metallurgy, textiles, petroleum, etc. The chemical industry is used to produce water glass, baking soda, etc. Used as a softening agent in the printing and dyeing industry. Used in the leather industry for degreasing raw hides. It is also used in the production of synthetic detergent additives.
Food grade soda ash is mainly used in the production of monosodium glutamate, noodles, etc.

Light soda ash is in powder form and mainly used for water treatment. Heavy soda ash is a small granular substance mainly used in glass production.
