Potassium bitartrate, also known as cream of tartar, has the chemical formula KC₄H₅O₆ and a CAS number of 868 - 14 - 4. It is a white, odorless, crystalline powder. The molar mass of potassium bitartrate is approximately 188.18 g/mol. It is freely soluble in hot water, but only slightly soluble in cold water. Potassium bitartrate is a by - product of the wine - making process and is widely recognized for its high purity and quality in the market, especially our high - quality product which offers the best price.
In the culinary world, potassium bitartrate is a versatile ingredient. It is commonly used in baking as a leavening agent. When combined with baking soda, it forms a reaction that helps dough and batters rise, resulting in lighter and fluffier baked goods such as cakes, muffins, and pancakes. It can also be added to egg whites when whipping to increase their stability and volume, making them ideal for meringues and soufflés.
In the chemical industry, potassium bitartrate is used as a buffering agent due to its acidic nature. It helps maintain the pH balance in various chemical reactions and solutions. Additionally, it can be used as a reducing agent in some chemical processes.
In the medical field, potassium bitartrate is sometimes used in the preparation of certain medications. It can also be used as a laxative in some cases, although this usage should be under the guidance of a medical professional.
Culinary Use
When using potassium bitartrate in baking, for every 1/4 teaspoon of baking soda, you can use about 1/2 teaspoon of potassium bitartrate. Mix them well before adding to the dry ingredients of your recipe. When whipping egg whites, add about 1/8 teaspoon of potassium bitartrate per egg white at the beginning of the whipping process. This will help the egg whites reach stiff peaks more easily and hold their shape better.
Chemical Use
In a chemical laboratory, the amount of potassium bitartrate used depends on the specific reaction and the desired pH level. It is usually added gradually while monitoring the pH with a pH meter. Make sure to dissolve it in hot water first if a faster reaction is required.
Medical Use
As mentioned, if using as a laxative, it should be done under medical advice. The dosage will be determined by a doctor based on the patient's condition.
Bakery Case
A local bakery was having issues with their cakes being too dense. After consulting with a baking expert, they started using potassium bitartrate in their cake recipes. By adding 1/2 teaspoon of potassium bitartrate for every 1/4 teaspoon of baking soda in their cake batter, the cakes became much lighter and fluffier. The customers noticed the improvement, and the bakery's sales of cakes increased significantly.
Chemical Laboratory Case
In a research laboratory, a team was conducting a chemical reaction that required a stable pH environment. They added potassium bitartrate as a buffering agent. By carefully calculating and adding the appropriate amount of potassium bitartrate, they were able to maintain the desired pH throughout the reaction, which led to more consistent and accurate experimental results.
