1. Zamani:
SO2+2NaOH===Na2SO3+H2O
H2SO3 + Na2CO3 = = rubuta Na2SO3 + CO2 + H2O
2 nahso3 = = delta = Na2SO3 + H2O + SO2 rubuta
2. Ragewa:
3 na2so3 hno3 + 2 + 2 = = = 3 na2so4 ba rubuta + H2O
2Na2SO3+O2====2Na2SO4
3. The dumama:
4 na2so3 = = delta = = Na2S + 3 na2so4
4. Oxidation:
Na2SO3 + 3 h2s = = 3 s hagu + Na2S + 3 h2o [1]
