In the Cyanide Destruction by Hypochlorite reaction, the pH has a strong inverse effect on the ORP Thus, wastewater treatment facilities must closely control the pH to achieve consistent ORP control, especially if they use hypochlorite as the oxidizing agent Adding hypochlorite raises the pH, which, if unchecked, lowers the ORP calling for additional hypochlorite...
