Product Description
D-(-)-tartaric acid is widely used as an acidifier in beverages and food, similar to citric acid. It can also be used as a mordant for acid dye when combined with tannin. In the photographic industry, tartaric acid is used for some development and fixing processes. Its iron salts are photosensitive, making them suitable for blueprint production. Tartaric acid has the ability to form complexes with various metal ions, making it effective as a cleaning and polishing agent for metal surfaces. Potassium tartrate, known as Rochelle salt, is used to prepare Fehling reagent and is also employed as a laxative and diuretic in medicine. It is used as an intermediate for the synthesis of quinophan. Due to its piezoelectric properties, tartaric acid crystals find application in the electronics industry.
