Tartaric acid is widely used as an acidifier in beverages and other foods, which is similar to citric acid. Tartaric acid combined with tannin can be used as a mordant for acid dyes, and also for some developing and fixing operations in the photographic industry. Its iron salt is photosensitive, so it can be used to make blueprints. Tartaric acid can be complexed with various metal ions and can be used as cleaning agent and polishing agent for metal surface. Potassium sodium tartrate (Rochelle salt) can be used to prepare Fehling reagent, and can also be used in medicine as a laxative and diuretic, and also as an intermediate of Cincofene. Its crystal has piezoelectric properties and can be used in electronic industry. Used as chromatographic analysis reagent and masking agent, as pharmaceutical resolution agent, food additive, biochemical reagent, etc
