Sulfuric acid dipotassium salt

Description:

Sulfuric acid dipotassium salt, also known as dipotassium sulfate (K2SO4), is an inorganic compound characterized by its white crystalline appearance and high solubility in water. It is a neutral salt formed from the reaction of sulfuric acid with potassium hydroxide or potassium carbonate. Dipotassium sulfate is commonly used as a fertilizer in agriculture due to its ability to provide essential potassium and sulfur nutrients to plants, promoting healthy growth and improving crop yields. In addition to its agricultural applications, it is utilized in various industrial processes, including the manufacture of glass, detergents, and as a drying agent in chemical reactions. The compound has a relatively high melting point and is stable under normal conditions, making it suitable for various applications. Its hygroscopic nature allows it to absorb moisture from the environment, which can be a consideration in storage and handling. Overall, dipotassium sulfate is valued for its dual nutrient contribution and versatility in both agricultural and industrial contexts.

Potassium sulfate

CAS: 7778-80-5

Potassium sulfate is a salt of potassium and sulfuric acid. It has a synergistic effect with sodium salts in the treatment of water hardness, which leads to a phase transition temperature below that of sodium sulfate alone. Potassium sulfate is also used as an analytical reagent for the determination of sulfate in solution. The reaction solution is heated to release the adsorbed gas, which is then analyzed by gas chromatography or infrared spectroscopy. Structural analysis was performed using X-ray crystallography on potassium sulfate crystals. Potassium sulfate has been shown to have physiological effects such as an increase in the concentration of iron in blood plasma and an increase in phosphate excretion from the kidneys at high doses. It has also been shown to have biological properties such as thermal expansion and phosphorus pentoxide reactivity.
