Sodium tartrate

Sodium tartrate is a white, crystalline salt that is used in medicine to treat certain types of muscle spasms and cramps. It is also used as a mild laxative and to reduce the symptoms of gout. Sodium tartrate is available as a tablet, capsule, or syrup and can be taken orally. It is also used in the manufacture of food and medicines.

Sodium tartrate is not exactly a medicinal substance, but it is generally recognized as safe (GRAS) for use in food by the US Food and Drug Administration (FDA) [1]. It's more commonly found as a food additive.

Here's a breakdown of sodium tartrate:

• Chemical compound: Sodium tartrate is a salt formed by neutralizing tartaric acid with sodium hydroxide [1].
• Chemical formula: C4H4Na2O6 (anhydrous) or C4H8Na2O8 (dihydrate) [1].
• Appearance: White crystals [1].
• Uses in food: Emulsifier and a binding agent in food products such as jellies, cheese, margarine, and sausage casings [1, 6]. It has the E number E335 [1].
• Other uses: A primary standard for Karl Fischer titration, a technique used to measure water content in a substance [1].
