The chemical formula of potassium bitartrate is KC₄H₅O₆.
Potassium bitartrate, more commonly recognized as cream of tartar, is a versatile chemical compound with a variety of applications, particularly in culinary arts and household cleaning. It is also known by its chemical name, potassium hydrogen tartrate.
Understanding Potassium Bitartrate (Cream of Tartar)
This compound is the potassium acid salt of tartaric acid, a carboxylic acid found naturally in many plants, especially grapes. It often crystallizes inside wine barrels during the fermentation of grape juice, where it's collected and refined for commercial use.
Key Characteristics and Composition
The formula KC₄H₅O₆ reveals its elemental composition:
- K represents one atom of Potassium.
- C₄ indicates four atoms of Carbon.
- H₅ denotes five atoms of Hydrogen.
- O₆ signifies six atoms of Oxygen.
This specific arrangement of atoms gives potassium bitartrate its unique chemical properties, making it an invaluable ingredient in many contexts.

Diverse Applications
Potassium bitartrate's utility spans across several domains due to its acidic nature and stabilizing properties:
- Culinary Uses:
- Baking: It is a key ingredient in baking powder, reacting with baking soda to produce carbon dioxide, which helps doughs and batters rise.
- Stabilizer: It stabilizes egg whites, increasing their heat tolerance and volume when whipped into meringues, soufflés, or frosting. It also prevents sugar syrups from crystallizing.
- Leavening Agent: When combined with an alkaline ingredient (like baking soda), it acts as a leavening agent in baked goods.
- Household Cleaning:
- Can be mixed with lemon juice or vinegar to create a mild abrasive paste for cleaning metal surfaces like copper, brass, and stainless steel.
- Effective for removing stains from porcelain.
- Other Uses:
- In some traditional dyeing processes, it acts as a mordant to help dyes adhere to fabric.
- Used in some medical applications as a laxative.
