Potassium Sodium Tartrate, with the CAS number 304 - 59 - 6, is a well - known chemical compound. It is also known as Rochelle salt. The molecular formula of Potassium Sodium Tartrate is (C_4H_4KNaO_6cdot4H_2O). The molar mass of the tetrahydrate form is approximately 282.22 g/mol.
It appears as colorless to white, odorless, and transparent crystals or crystalline powder. It has a sweetish, cooling taste. The product is highly soluble in water, with solubility around 139 g/100 mL at 20°C. It is insoluble in alcohol. It has a melting point of about 70 - 80°C (loses water of crystallization), and decomposes above this temperature.
1. **In the Food Industry**: Potassium Sodium Tartrate is used as an emulsifier, stabilizer, and acid regulator. It can help maintain the stability of food products, such as in some dairy products and processed meats. For example, it can prevent the coagulation of milk proteins in certain dairy beverages, ensuring a smooth texture.
2. **In the Pharmaceutical Industry**: It is used as a laxative in some formulations. The compound can increase the water content in the intestines, promoting bowel movements. It is also used as a buffering agent in some pharmaceutical preparations to maintain the appropriate pH value.
3. **In the Chemical Laboratory**: It is a common reagent in various chemical analyses. For instance, it is used in the Fehling's solution, which is used to detect reducing sugars. It can also be used in the preparation of buffer solutions.
4. **In the Electroplating Industry**: Potassium Sodium Tartrate can be used as a complexing agent. It helps in controlling the deposition rate of metal ions during the electroplating process, improving the quality and appearance of the electroplated layer.
1. **In Food Applications**: When using it as an emulsifier or stabilizer in food production, first, dissolve the appropriate amount of Potassium Sodium Tartrate in a small amount of water at room temperature. Then, add the solution to the food mixture gradually while stirring continuously. The dosage should be determined according to the specific food product and relevant food safety standards.
2. **In Pharmaceutical Preparations**: For laxative use, it should be taken orally as directed by a doctor. Usually, it is dissolved in a glass of water and consumed. When used as a buffering agent, calculate the required amount based on the pH requirements of the pharmaceutical formulation and add it during the preparation process.
3. **In Laboratory Work**: In chemical analyses, accurately weigh the required amount of Potassium Sodium Tartrate according to the experimental procedure. Dissolve it in a suitable solvent, such as distilled water, and use it in the subsequent reactions. When preparing buffer solutions, follow the standard buffer - preparation methods and adjust the pH as needed.
4. **In Electroplating**: Dissolve the compound in the electroplating bath solution. The concentration of Potassium Sodium Tartrate in the bath should be optimized through preliminary experiments to achieve the best electroplating effect. Continuously monitor the bath parameters during the electroplating process.
1. **Food Industry Case**: A dairy company was facing the problem of protein coagulation in its new fruit - flavored milk beverage. By adding 0.5% Potassium Sodium Tartrate as an emulsifier, the stability of the beverage was significantly improved. After a three - month storage test at room temperature, there was no visible coagulation or separation in the product, which met the market requirements for product quality.
2. **Pharmaceutical Industry Case**: A pharmaceutical factory was developing a new laxative formulation. By using Potassium Sodium Tartrate as the main active ingredient, a clinical trial was conducted on 100 patients with constipation. The results showed that within 24 hours after taking the medicine, 80% of the patients had significant improvement in bowel movements, indicating the effectiveness of the compound in treating constipation.
3. **Laboratory Case**: In a chemical analysis laboratory, researchers were using Fehling's solution to detect reducing sugars in a fruit juice sample. By accurately preparing the Fehling's solution with
