Pròiseas cinneasachaidh #sodiumsulfite

Tha sulfa is èadhar air an losgadh gus gas SO2 a ghineadh.

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 solution.

After concentration and centrifugation, a wet solid of #sodiumsulfite is obtained and dried. Then get the finished sodium sulfite

Tha am foirmle ath-bhualadh mar a leanas:

S + O2 = SO2

SO2 + Na2CO3 + H20 = NaHSO3

NaHSO3 + NaOH = Na2SO3 + H20
