Potassium bitartrate, also known as potassium hydrogen tartrate, has formula KC4H5O6. It is a byproduct of winemaking. It is also known as cream of tartar. It is the potassium acid salt of tartaric acid.
This crude form (known as beeswing) is collected and purified to produce the white, odorless, acidic powder used for many culinary and other household purposes.
A similar acid salt, sodium acid pyrophosphate, is confused with cream of tartar due to their similar function in baking powder.
Can be used with white vinegar to make a paste-like cleaning agent.
