  2. Free Chlorine • Free Chlorine exists as • Hypochlorite Ions OCl • Hypochlorous Acid (HOCl) File Name: Chlorine.ppt

  3. Free Chlorine Sensor • ORP Reaction • HOCl diffuses through the membrane and is reduced at the gold cathode to chloride ions and hydroxide ions. • Silver is oxidized to silver chloride at the anode. • The current flow is directly proportional to the free chlorine concentration. File Name: Chlorine.ppt
