Q7. This question is about methods of treating water. (a) Chlorine is used to kill microorganisms in water. When chlorine is added to water a chemical reaction takes place. The equation for this reaction is shown below. Cl 2 (g) + H 2 O(l) 2H+(aq) + OCl–(aq) + Cl–(aq) An acidic solution is produced when chlorine reacts with water.
