KGM KYOTO ELECTRONICSMANUFACTURING CO.,LTD.TIQ-97057enL-K-M KYOTO ELECTRONICSMANUFACTURING CO.,LTD. Application MemoChlorine Ion in Metal Cleanser 1.Overview Chlorine ion concentration in metal cleanser is measured by potentiometric titration.First, thesample is added with water and nitric acid solution, and then titrated with 0.1mol/L silvernitrate solution up to the endpoint. The endpoint is the maximum inflexion on the titrationcurve. The concentration of chlorine ion is calculated from the titration volume of silvernitrate. 2. Apparatus Main unit Automatic potentiometric titrator (preamplifier STD) Electrode Silver electrode Mercury sulfate reference electrode 3. Reagents Titrant 0.1mol/L silver nitrate solutionAdditive Nitric acid solution 4. Example Sample Titer Chlorine ion (g) (mL) (ppm) 1 2 3 5.1315 1.2638 874.30 5.1138 1.2610 875.39 5.1206 1.2589 872.77 AverageSD RSD(%) 872.15 1.32 0.151 -Titration curve- Please feel free to contact us for any further information.
