薄膜清洗液中盐酸含量的测定 应用资料将样品加入纯水后，用1mol/L氢氧化钠滴定溶液滴定至终点，测量盐酸含量。终点是滴定曲线上的最大拐点。盐酸浓度是根据氢氧化钠的滴定体积计算得出的。KGMKYOTO ELECTRONICSMANUFACTURING CO.，LTD.TII-93002enL Application Memo Hydrochloric Acid in Film Cleaning Liquid Industry Plastic，Rubber Instrument Automatic potentiomet r ic titrator Measurement methodAcid-base titration StandardsGB/T 320 1.Overview Hydrochloric acid is measured by titration with 1mol/L sodium hydroxide up to the endpoint after the sample is added with pure water. The endpoint i s t he maximum inflexion on t he titration curve. Hydrochloric acid concentration is calculated from the t i tration volume of sodium hydroxide. 2.
