S+O2= SO2S+H2SO4(浓)= 3SO2↑+2H2O
S+6HNO3(浓)= H2SO4+6NO2↑+2H2O
S+4H++6==6NO2↑+2H2O+
3S+4HNO3(稀) =3SO2+4NO↑+2H2O
3S+4H++4HNO3 = 3SO2+4NO↑+2H2O
Cl2+Na2S===2NaCl+S↓ Cl2+S2–=2Cl–+S↓
Cl2+H2S===2HCl+S↓ (水溶液中:Cl2+H2S=2H++2Cl–+S↓
Cl2+SO2+2H2O===H2SO4+2HCl
Cl2+SO2+2H2O=4H++SO42–+2Cl–
S+H2 H2S 2S+C CS2 S+Zn ZnS
S+Fe FeS (既能由单质制取,又能由离子制取)
S+2Cu Cu2S (只能由单质制取,不能由离子制取)
3S+2Al Al2S3 (只能由单质制取,不能由离子制取)
