Cl2+H2O==HCl+HClO
Cl2+2NaOH===NaCl+NaClO+H2O
2Cl2+2Ca(OH)2===CaCl2+Ca(ClO)2+2H2O
Cl2+2FeCl2===2FeCl3
Ca(ClO)2+H2O+ CO2(少量)== Ca CO3↓+2 HClO
Ca(ClO)2+2H2O+ 2CO2(多量)== Ca(HCO3)2↓+2 HClO
Ca(ClO)2+2 HCl == Ca Cl2+2 HClO(强酸制弱酸)
2HClO==2HCl+O2↑
2Cl2+2NaBr===2NaCl+Br2
Cl2 +2 K I ===2 K Cl+I2
HCl + AgNO3 === AgCl↓+ HNO3
Br2 +2 K I ===2 K Br+I2
4HCl(浓)+MnO2==MnCl2+Cl2↑+2H2O
HCl + AgNO3 === AgCl↓ + HNO3
HCl + AgNO3 =AgCl↓(白色)+HNO3
