Tastes salty and cool.

Application:
Potassium sodium tartrate tetrahydrate, also known as Rochelle salt, is a double salt of Tartaric Acid first prepared by an apothecary, Pierre Seignette, of La Rochelle, France. Potassium Sodium Tartrate and monopotassium phosphate were the first materials discovered to exhibit piezoelectricity.This property led to its extensive use in "crystal" gramophone pick-ups, microphones and earpieces during the post-World War II consumer electronics boom of the mid-20th Century. Such transducers had an exceptionally high output with typical pick-up cartridge outputs as much as 2 volts or more. Rochelle salt is deliquescent so any transducers based on the material deteriorated if stored in damp conditions.
In the pharmaceutical industry, it is used to prepare Flynn's solution and test reducing sugar, and is used as a laxative. In the electroplating industry, it is used as chemical copper precipitation and as a complexing agent in cyanide copper plating. In the chemical industry, it is used as a desulfurizer for natural chemicalbook gas. In the food industry, it is used to prepare baking powder. In the mirror industry, it is used for silver mirror reactions, etc. As a chemical reagent, it is mainly used as a masking agent and used in biochemical tests of serum proteins.

what is Tartaric acid ?
Tartaric acid is commonly used in the preparation of medicines, mordants and tanning agents, and is also commonly used as a reagent for the resolution of racemic basic compounds. It is also a sour agent in food additives, sourness is better than malic acid, lactic acid and so on. Several of its salts have important applications. For example, the Fehling reagent is formulated with potassium sodium tartrate in the laboratory to identify aldehyde functional groups in the structure of organic molecules. Its potassium and sodium salt is also called Rochelle's salt. Its crystals are polarized under pressure to produce a potential difference (piezoelectric effect) on both ends of the surface, which can be made into piezoelectric elements for radio and cable broadcasting. The receiver and pickup. Medically, potassium antimony tartrate (commonly known as tartrate) is used to treat schistosomiasis

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.
