We describe a procedure for the determination of hydrochloric acid concentration in gastric juice by means of a conductometric titration of the 50-fold diluted sample with an aqueous ammonia solution. The conductometric method of endpoint indication leads to a definite location of the equivalence point in the titration of hydrochloric acid. The proposed method is simple and accurate and shows a good correlation with an accepted method for the measurement of gastric acidity.
我们描述了一种通过用氨水溶液对50倍稀释的样品进行电导滴定来测定胃液中盐酸浓度的方法。终点指示的电导法可确定盐酸滴定中的等当点位置。所提出的方法简单且准确，与公认的胃酸测量方法具有良好的相关性。
