Potassium Sulfite, with the CAS number 10117 - 38 - 1, is a white crystalline powder. It has a molecular formula of K₂SO₃ and a molecular weight of approximately 158.26 g/mol. The product is supplied directly from the factory, ensuring high - quality standards and competitive prices. It is highly soluble in water, and its aqueous solution shows alkalinity due to hydrolysis. In terms of purity, our factory - supplied Potassium Sulfite can reach a high level, meeting the strict requirements of various industries. It should be stored in a cool, dry, and well - ventilated place, away from sources of ignition and incompatible substances.
1. **Food Industry**: Potassium Sulfite is widely used as a food preservative and antioxidant. It can prevent the oxidation of food, maintain the color, flavor, and nutritional value of food products. For example, it is commonly used in dried fruits to prevent browning and in wine - making to inhibit the growth of bacteria and yeasts, thus extending the shelf - life of the wine.
2. **Textile Industry**: In the textile industry, it serves as a reducing agent. It can be used in the bleaching and dyeing processes to remove excess oxidants and improve the quality of the fabric. It helps to achieve more uniform dyeing and better color fastness.
3. **Photographic Industry**: It is an important component in photographic developers. It can prevent the oxidation of developing agents, ensuring the stability and effectiveness of the developing process.
4. **Chemical Industry**: Potassium Sulfite is used as an intermediate in the synthesis of various chemicals. It can react with other substances to produce new compounds with specific properties.
1. **Food Industry**: When using Potassium Sulfite as a food additive, it should be added in accordance with the relevant national food safety standards. First, dissolve the appropriate amount of Potassium Sulfite in water to form a solution. Then, add the solution to the food during the processing stage. The dosage should be carefully controlled to ensure food safety and quality.
2. **Textile Industry**: In the textile bleaching and dyeing processes, prepare a solution of Potassium Sulfite with a suitable concentration according to the specific requirements of the fabric and the process. Immerse the fabric in the solution for a certain period of time, and then carry out subsequent washing and drying steps.
3. **Photographic Industry**: For photographic developers, follow the recipe of the developer formula. Add the required amount of Potassium Sulfite to the developer solution, and mix well to ensure uniform distribution.
4. **Chemical Industry**: In chemical synthesis, the reaction conditions such as temperature, pressure, and reaction time should be strictly controlled according to the specific reaction requirements. Potassium Sulfite should be added gradually during the reaction process to ensure the smooth progress of the reaction.
1. **Food Industry Case**: A fruit - drying company used Potassium Sulfite as a preservative. They added a 0.5% Potassium Sulfite solution to the freshly cut apples before drying. After the drying process, the apples retained their original color and flavor, and the shelf - life was extended from 1 month to 3 months. This not only improved the product quality but also reduced the economic losses caused by spoilage.
2. **Textile Industry Case**: A textile factory used Potassium Sulfite in the dyeing process of cotton fabrics. By adding a 2% Potassium Sulfite solution during the dyeing process, they achieved more uniform color distribution on the fabric. The color fastness of the dyed fabric was also significantly improved, meeting the high - quality requirements of the market.
3. **Photographic Industry Case**: A photography studio used a developer solution containing Potassium Sulfite. The developed photos had clear images and accurate colors. The Potassium Sulfite effectively prevented the oxidation of the developing agents, ensuring the stability and repeatability of the developing process.
4. **Chemical Industry Case**: A chemical company synthesized a new compound using Potassium Sulfite as an intermediate. By strictly controlling the reaction conditions and the amount of Potassium Sulfite added, they successfully obtained the target compound with a high yield of over 90%, which laid a good foundation for subsequent large - scale production.
