What types of soda ash are there on the market?
Are you talking about heavy soda ash or low-sulfur, low-salt heavy soda ash prepared from trona?
Reply 1# shen308 Light soda ash is commonly known as light ash, heavy soda ash is commonly known as heavy ash

It can be divided into three types: light soda ash, heavy soda ash and edible soda ash.
That is to say, there are two types: light alkali and heavy alkali. The industrial name of the one without crystallization water is light alkali, and the industrial name of the one with crystallization water is heavy alkali.
It can be divided into two types: light gray alkali and heavy gray alkali. Heavy gray alkali is formed after passing through a hydration machine and calcining the same light gray alkali.
Strictly speaking, edible alkali is also a light alkali.
Can the components of various bases be directly expressed using molecular formulas?
The components of light alkali and heavy alkali are the same, both are Na2CO3, so they cannot be directly expressed by molecular formulas. However, the production of heavy alkali is the combination of light ash and water to form monohydrate alkali (Na2CO3·H2O), which is produced after calcination. The specific gravity of the light alkali is different due to the crystal lattice.
Doesn’t it include trona? What kind of trona is it? I don’t understand. Is trona alkali directly mined?
