What is potassium sodium tartrate used for?
It is an ingredient of Fehling’s solution (reagent for reducing sugars). It is used in electroplating, in electronics and piezoelectricity, and as a combustion accelerator in cigarette paper (similar to an oxidizer in pyrotechnics).
What is the role of potassium sodium tartrate in Fehling’s test?
Fehlings soluition is alkaline. Mixing cupric ions with an alkaline solution would result in formation of cupric hydroxide of very low water solubility. By adding tartrate ions, the cupric ions will form a complex with the cupric ions which will keep them dissolved in the alkaline solution.
Is sodium potassium tartrate and potassium sodium tartrate same?
Sodium potassium tartrate is a double salt of tartaric acid with a chemical formula C4H4O6KNa·4H2O. It is also known as Rochelle salt or Potassium sodium tartrate.
What are the 4 uses of potassium tartrate?
It is obtained as a byproduct of wine manufacture during the fermentation process. Approved by the FDA as a direct food substance, potassium bitartrate is used as an additive, stabilizer, pH control agent, antimicrobial agent, processing aid, or thickener in various food products 3.
What is the functions of tartrate?
The main forms of tartrates used commercially are pure crystalline tartaric acid used as an acidulant in non-alcoholic drinks and foods, cream of tartar used in baking, and Rochelle salt, commonly used in electroplating solutions.
Is potassium sodium tartrate hazardous?
May be harmful if absorbed through the skin. Ingestion: May cause irritation of the digestive tract. May be harmful if swallowed. Inhalation: May cause respiratory tract irritation.
How does sodium potassium tartrate dissolve?

What kind of salt is sodium potassium tartrate?
Potassium sodium L-tartrate is the organic sodium and potassium salt of L-tartaric acid (mol ratio 1:1:1). It has a role as a laxative. It is a potassium salt and an organic sodium salt. It contains a L-tartrate (2-).
Is it safe to use potassium tartrate in food?
Sodium potassium tartrate used as a general purpose food additive in animal drugs, feeds, and related products is generally recognized as safe when used in accordance with good manufacturing or feeding practice.
What is the E number of sodium tartrate?
As a food additive, it is known by the E number E335. Because its crystal structure captures a very precise amount of water, it is also a common primary standard for Karl Fischer titration, a common technique to assay water content.
How is sodium tartrate used in organic synthesis?
In organic synthesis, it is used in aqueous workups to break up emulsions, particularly for reactions in which an aluminium-based hydride reagent was used. Sodium Potassium tartrate is also important in the food industry.
