C6H7KO6

C6H7KO6 is a chemical formula representing potassium hydrogen tartrate, also known as cream of tartar. It is a potassium acid salt of tartaric acid.

Cream of tartar is a white, odorless, crystalline powder. It is a byproduct of winemaking. Specifically, it forms as a deposit on the inside of wine barrels during fermentation. The crude form, known as argol, is purified to produce cream of tartar.

In culinary applications, cream of tartar is used as a stabilizer for egg whites, increasing their volume and preventing collapse. It is also used as an ingredient in baking powder, functioning as an acid component. Furthermore, it can be used to prevent sugar syrups from crystallizing and as a leavening agent in some baked goods.

Chemically, potassium hydrogen tartrate is a salt formed by the partial neutralization of tartaric acid with potassium hydroxide or potassium carbonate. The presence of the hydroxyl groups and carboxyl group in the tartaric acid molecule allows for salt formation with a metal like potassium. It's also slightly soluble in water.
