柚子酱油中食盐含量的测量 应用资料通过用0.1mol/L硝酸银溶液滴定来测量稀释样品中的盐含量的浓度。终点是滴定曲线上的最大拐点。盐含量度浓度根据终点处硝酸银溶液的滴定体积计算。KGM KYOTO ELECTRONICSMANUFACTURING CO.,LTD.TIF-97002enL-K-MKYOTO ELECTRONICSMANUFACTURING CO.,LTD. Application Memo Measurement of Salt Content in Ponzu Soy Sauce 1.Overview Salt concentration in the diluted sample is measured by titration with 0.1mol/L silver nitratesolution. The endpoint is the maximum inflexion on the titration curve. The salt concentrationis calculated from the titration volume of the silver nitrate solution at the endpoint. 2.
