WebEdition). The scope of this application note is to determin e the total chlorine concentration (= Free Chlorine Conc. + Combined Chlorine Conc.) in water or waste water samples. By using a back titration, the chlorine concentration is fixed at the collection of the sample, allowing the sample to be stored for later analysis. WebThe purpose of this experiment is to compare two titrimetric methods for the analysis of chloride in a water-soluble solid. The two methods are: • a weight titration method using …
