回答1:

H2S+Br2=2HBr+S(沉淀)

SO2 + Br2 + 2H2O = 2HBr + H2SO4

Na2S+Br2→2NaBr+S↓

Na2SO3+Br2+H2O==Na2SO4+2HBr

回答2:

Br2 + SO2 + 2H2O → H2SO4 + 2HBr

Br2 + Na2SO3 + H2O → H2SO4 + 2NaBr

H2S + Br2 → 2HBr + S↓

Na2S + Br2 → 2NaBr + S↓

回答3:

Br2+H2S===S +2HBr Br2+SO2+2H2O==H2SO4+2HBr Br2+Na2S==S+2NaBr
Br2+Na2SO3+H2O==Na2SO4+2HBr
