Information
What is Potassium Sodium Tartrate? | All About Rochelle Salt
Potassium sodium tartrate, also known as Rochelle salt or Seignette's salt, is a chemical compound with the formula KNaC₄H₄O₆·4H₂O. It is the double salt of tartaric acid containing both sodium and potassium ions and is widely used in industrial, analytical, and scientific applications.
This compound appears as colorless to white crystals that are highly soluble in water. It was originally discovered in the 17th century in the French city of La Rochelle — hence the name "Rochelle salt".
Applications of Potassium Sodium Tartrate
Potassium sodium tartrate has a wide range of uses across various sectors:
1. In Analytical Chemistry
-
Used as a complexing agent in titrations, especially for detecting metals like copper, aluminum, and nickel.
-
Plays a key role in Fehling’s solution, which is used to test for the presence of reducing sugars.
2. In the Pharmaceutical Industry
-
Occasionally used as a mild laxative.
-
Can act as a stabilizer in certain medicinal formulations.
3. In Electrical Engineering
-
Rochelle salt is a piezoelectric material: it generates an electric voltage when subjected to pressure. For this reason, it is used in specific types of sensors, microphones, and crystal oscillators.
4. In Laboratories
-
Used as a buffer solution or in crystallization processes.
-
Ideal for experiments requiring specific pH conditions.
