How to detect the chlorine content in sodium hypochlorite?
Thread Content
Are there any other methods besides using instruments to measure the chlorine content in sodium hypochlorite?
Of course there is. The available chlorine in sodium hypochlorite can be determined by the iodometric method (a redox titration). This testing method is specified in the product standards for sodium hypochlorite. For total chlorine, the available chlorine in the sample must first be completely converted into chloride ions before titration using the silver method.
