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 …

WebCD-ROM 9253 - 3 Revision 0 September 1994 7.5 Calculation 7.5.1 Calculate the chloride ion concentration in the original sample, in milligrams per liter, as follows: Chloride (mg/L) = [(V 1 - V 2) x N x 71,000] / S where: V 1 = Milliliters of standard AgN0 3 solution added in titrating the sample prepared in Sec. 7.1. V WebA) so that the color of the solution at the end of the titration indicates whether the sample is above 1,000 µg/g chlorine (yellow) or below 1,000 µg/g chlorine (blue). 2.3 The first quantitative kit (Method B) involves a reverse titration of a fixed volume of mercuric nitrate with the extracted sample such that the en d WebAmperometric titration is the standard method for comparison of accuracy in determining residual chlorine in drinking water. FAC is determined by titration with a standard solution of As (III) (in the form of phenylarsine oxide, C 6 H 5 AsO) at a pH between 6.5 and 7.5. a5公分數
