Used as chromatographic analysis reagent and masking agent.
Use 3
Tartaric acid is widely used as an acidifier in beverages and other foods, a use similar to citric acid. Tartaric acid is used in combination with tannin as a mordant for acidic dyes, and is also used in certain development and fixing operations in the photographic industry, and its iron salts are photosensitive, so they can be used to make blueprints. Tartaric acid can be complexed with a variety of metal ions, and can be used as a cleaning agent and polishing agent for metal surfaces. Potassium sodium tartrate (Rochelle salt) can be formulated as a Fehring reagent, can also be used in medicine as a laxative and diuretic, and is also used as an intermediate of Cinchophen. Its crystals have piezoelectric properties and can be used in the electronics industry.
