蚀刻液中乙酸(冰醋酸)含量的测定 应用资料样品加入纯水后，用0.5mol/L氢氧化钠滴定溶液测定蚀刻剂中的乙酸(冰醋酸)含量。滴定上升到终点，即滴定曲线上的最大拐点。乙酸(冰醋酸)浓度由氢氧化钠的滴定体积计算。KGM KYOTO ELECTRONICSMANUFACTURING CO.，LTD.TIQ-97008enL Application Memo Acetic Acid of Etching Solution 1.Overview Acetic acid in etchant i s measured by titration with 0.5mol/L sodium hydroxide after the sample is added with pure water. Titration goes up to the endpoint which is t he maximum inflexion on the titration curve. The acetic acid concentration is calculated from the titration volume of sodium hydroxide. 2. Apparatus Main unit Automatic potentiometric titrator (preampli f ier STD) Electrode pH Glass electrode Ceramic reference electrode Temperature compensation electrode 3.
