Potassium Sulfate, also known as Sulfate of Potash, Dipotassium sulfate, and Potassium Sulfate (2:1), appears colorless or white crystals/crystalline powder having bitter saline taste and is Water- soluble at ambient conditions. When heated to decomposition, it emits toxic fumes of Sulfur Oxides. Lab grade chemicals possess reasonable purity but do not comply with any official standard for quality or purity like the ACS Grade, the USP Grade, or the FCC Grade. The Lab Grade is also known as Laboratory Reagent (LR) and Chemically Pure (CP). Lab Alley’s Potassium Sulfate, Lab Grade is recommended for educational institutes, research labs, and commercial applications.
Fertilizer: Potassium sulfate is a significant source of potassium, an essential nutrient for plant growth. It is commonly used in agriculture as a fertilizer to enhance crop yields and improve the quality of fruits, vegetables, and other crops. It is particularly favored in crops where chloride-sensitive crops, such as tobacco, grapes, and certain fruits, are grown.
Industrial Applications: Potassium sulfate is utilized in various industrial processes, such as the production of glass, ceramics, and glazes. It can act as a flux, helping to lower the melting point of materials and improve their flow properties during manufacturing.
Chemical Manufacturing: Potassium sulfate serves as a raw material in the manufacturing of various chemicals, including potassium carbonate, potassium hydroxide, and potassium alum. These chemicals are used in industries such as soap production, detergent manufacturing, and water treatment.
Laboratory Reagent: In laboratory settings, potassium sulfate is used as a reagent in chemical reactions and analytical procedures. It may be employed in precipitation reactions, as a source of potassium ions, or as a component of buffer solutions.
