NaC6H7O6

NaC6H7O6 represents the chemical formula for sodium tartrate. It is the sodium salt of tartaric acid. Tartaric acid is a naturally occurring organic acid found in many fruits, most notably grapes. Sodium tartrate typically exists as a white crystalline solid and is soluble in water. It is often encountered as a dihydrate, meaning it incorporates two molecules of water into its crystal structure.

The primary applications of sodium tartrate stem from its properties as an acidulant, emulsifier, and stabilizer. In the food industry, it is used as a food additive, often designated by the E number E335. It can contribute to the leavening process in baking when combined with baking soda. Furthermore, it finds use in pharmaceutical preparations and in some industrial processes, such as in electroplating and as a mordant in dyeing textiles. Sodium tartrate is also employed in analytical chemistry, particularly in Fehling's solution, a reagent used to detect the presence of reducing sugars. It is generally considered safe for consumption within established limits.
