Conductometric titration of hydrochloric acid in gastric juice.
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...
متن کاملGastric Juice I. Studies on the Proteins of the Gastric Juice of Humans
The studies to be reported were undertaken with the idea of throwing more light on the proteins of the gastric juice. It has been found that they can be precipitated by tungstic acid at pH 3.5 and that, although heating coagulated a protein, there remained in solution a heat-uncoagulable substance which gave a positive biuret reaction. Interest in the subject was stimulated by the investigation...
