TARTARIC ACID
Tartaric Acid
Tartaric acid, also known as 2,3-dihydroxybutanedioic acid is a white crystalline dicarboxylic, organic acid. It occurs naturally in many plants especially in fruits like grapes. Natural tartaric acid is produced from the by-products of wine fermentation. It has many applications including medicine, photography, dyes etc. It also has the property of being an antioxidant.

1g of tartaric acid dissolves in 162ml of cold water, in 16ml of boiling water, in 8820ml of alcohol. It is readily soluble in diluted mineral acids; it is soluble in aqueos solutions of borax and alkalies.
Tartaric Acid Uses:
- Glucose determination
- Mirror silvering
- Leather tanning
- manufacture of dyes used in textiles
- Used in the production of Rochelle salts sodium potassium tartrate
- Making of Blueprints
It is also used to clean and polish metals and in calico printing, wool dyeing, and photographic developing.
Tartaric acid in the Laboratory
Tartaric acid is used to prevent copper(II) ions from reacting with the hydroxide ions present in the preparation of copper(I) oxide. Copper(I) oxide is a reddish brown solid, and is produced by the reduction of a Cu(II) salt with an aldehyde, in an alkaline solution.
It finds use in making glucose determination solution for the purpose of medical analysis.
Tartaric acid and mirror silvering
Silvered mirrors are produced by applying a solution of ammoniacal silver nitrate which has been reduced with tartaric acid to the surface of the glass.
