根据有色配制酒“有色”这一特点，采用电极电位的“突跃”来指示终点的方法，提出了电位滴定法测定有色配制酒类总酸的方法；该法具有客观准确等优点，使电位滴定法广泛应用于无标准分析法测定各种有色配制酒类的总酸。
According to the characteristic of non-ferrous colored wine, the method of “sudden jump” of electrode potential is used to indicate the end point. The method of potentiometric titration for the determination of total acid in non-ferrous alcoholic liquor is proposed. The method has the advantages of objective and accurate, Titration is widely used in the absence of standard analytical methods for the determination of total acids in various colored alcoholic drinks.
