Determination of hydrochloric acid and nitric acid in etching baths using thermometric titration
Tóm tắt
Thermometric titration is used for the determination of hydrochloric acid and nitric acid in acid baths. The entire acid content is titrated with caustic soda in the initial titration; the hydrochloric acid content is then determined in a second titration using silver nitrate solution.
