Tsarin samarda #sodiumsulfite
Sulfur and air are incinerated to generate SO2 gas.
The SO2 gas reacts with a certain concentration of soda ash to generate sodium bisulfite.
Sodium bisulfite and caustic soda are neutralized to obtain #sodiumsulfite bayani.
After concentration and centrifugation, a wet solid of #sodiumsulfite is obtained and dried. Then get the finished sodium sulfite
The reaction formula is as follows:
SO2 + Na2CO3+H20= NaHSO3
NaHSO3+NaOH= Na2SO3 +H20
