1.
(1)2OH^- + Cl2 = Cl^- + ClO^- + H2O
(2)Ag^+ + Cl^- = AgCl
(3)2Fe^2+ + Cl2 = 2Fe^3+ + 2Cl^-
(4)SO3^2- + Cl2 + H2O = SO4^2- + 2Cl^- + 2H^+
(5)CO3^2- + 2H^+ = H2O + CO2
(6)2I^- + Cl2 = 2Cl^- + I2
2.
(1)Cl2 + SO2 + 2H2O = 4H^+ + SO4^2- + 2Cl^-,SO4^2- + Ba^2+ = BaSO4
(2)2NH3 + SO2 + H2O = 2NH4^+ + SO3^2-,SO3^2- + Ba^2+ = BaSO3
(3)3NO2 + H2O = 2H^+ 2NO3^- + NO,2H2O + 2NO3^- + 3SO2 = 2NO + 3SO4^2- + 4H^+,SO4^2- + Ba^2+ = BaSO4
(4)2H2S + SO2 = 3S + 2H2O
