Reactions of Chlorine - AS Chemistry

Chlorine sterilises water in the following equation:

2Cl + 2H2O <=> 4HCl + O2

The forward reaction has a colour change of green to colourless.  Water has been oxidised to Oxygen,and chlorine has been reduced to HCl

Chlorine also reacts with alkalis.  The products depend on the temperature.  At 15 degrees Celsius with a cold, dilute alkali, a solution of chloride and hypochlorite is…
