46. Final Jeopardy Label and describe what is happening in each zone (include X)

47. Breakpoint Chlorination Zone I: Chlorine is destroyed by reducing agents such as iron, manganese, clay and silt. Chlorine reduced to chloride Zone II: Chlorine comes into contact with organics and ammonia. Chloroorganics and chloramines are formed. Zone III: Chloroorganics and chloramines are partially destroyed. Chloramines are broken down and converted to nitrogen gas which leaves the system Zone IV: Breakpoint. Beyond this point, free available residual is formed. Some chloroorganics still remain as combined residual. Zone I: Chlorine is destroyed by reducing agents such as iron, manganese, clay and silt.
