Abstract
As a composite indicator of water, alkalinity is usually measured with titration analysis. Though it is a simple method, color judgment at the end point of titration is essen-tial to measurement result. Experiment was carried out based on theory, to determine the pH value of titration sample reaching end-point color and obtain the color standard for judgment of titration end point, which was applied in everyday inspection analysis, enabling analysis re-sults to effectively guide production.关键词
