Results: Determine the end-pointoftitration by sudden potential change of the indicatory electrode (use E-V curve method).
结果:指示电极电势突变时,为滴定终点(选用e V曲线法)。

During the production, determination of SO_2 (sulphur dioxide) in dry red wine using potentiometric titration avoids the end-point recognition difficulty compared with using iodometry method.
在生产中利用电位滴定法测定干红葡萄酒中SO_2的含量,避免了直接碘量法终点识别的困难。
