WebAdd a few drops of starch indicator solution. If the sample turns blue/purple, chlorine is present and must be removed. Titrate with Na2SO3 solution to dissipate the color. Add a proportional amount of Na2SO3 solution to the sample to be tested. Be careful not to overdose with Na2SO3 as this solution has an oxygen demand of its own. WebIf chlorine cannot overcome the oxidant demand, your water's chlorine demand rises, and the ORP drops. This would look like a more prolonged downward trend toward breakpoint, because breakpoint would be at a much higher dose of chlorine. When the chlorine can meet the oxidant demand, the water has reached breakpoint chlorination. teaching jobs in china for zimbabweans
