868-14-4 Usage


Largely in baking powders; coloring metals, galvanic tinning of metals; reducer of CrO3 in mordants for wool.

Chemical Properties

Also known as cream of tartar and potassium acid tartrate, KHC4H4O6 is white water soluble crystals or powder that is used in baking powder, for medicine, and as an acid and buffer in foods.

Purification Methods

It crystallises from water (17mL/g) between 100o and 0o. Dry it at 110o. [Beilstein 3 IV 1222.]

L (+)-Potassium hydrogen tartrate (also known as potassium bitartrate) is the potassiumacid salt of tartaric acid (a carboxylic acid). It is the byproduct during the winemaking process. It can be used in baking or as a cleaning solution. When mixed with an acidic liquid such as lemon juice or white vinegar, it can be made of a paste-like cleaning agent for metals or some other cleaning applications. It can also be used as a pH buffer component in chemistry. It has been recently shown that it is capable of treating breast cancer.
