General description

Water in public and private swimming pools must be disinfecting to kill bacteria and viruses. Chlorine-containing preparations or even chlorine gas itself are usually used for this purpose. To check the content of chlorine and the pH value is essential.

How to Prepare a Standard for Free Chlorine Analysis

AQA Standard for free chlorine - Preparation of a standard solution for free chlorine - Preparation of a stock solution of free chlorine: First prepare a 1:10 dilution using a sodium hypochlorite solution containing approximately 6 - 14 % of active chlorine. For this pipette 10 ml of sodium hypochlorite solution into a calibrated or conformity-checked 100-ml volumetric flask and then make up to the mark with water for analysis.
