Matters needing attention	Before use, it should be kept at (20±5) ℃ and shaken sufficiently to ensure uniformity. This reference materialshould be used once after opening, Strictly prevent contamination during use.
Reference material	Air and Waste Gas Monitoring and Analysis Methods 4th Edition, Water and Waste Gas Monitoring and Analysis Methods 4th Edition - State Environmental Protection Administration.
Physical and chemical properties	Density: 2.662(20 ℃) Melting point: 1069 ℃ Boiling point: 1689 ℃ Character: colorless or white crystal or powder, bitter and salty. Dissolution: soluble in water, insoluble in ethanol, acetone and carbon disulfide. Uses: Used as medicine (laxative), fertilizer, and used to make alum, glass and carbonated Potassium. Used as fertilizer is the main variety of chlorine-free Potassium fertilizer, mainly used in flax, tobacco, tea, citrus and other chlorine-free Potassium crops. Preparation or source:(1) It is prepared by the interaction of chlorinated Potassium and sulfuric acid. (2) It is prepared from anhydrous Potassium magnesite. (3) It is prepared from Potassium salt magnesium alum. (4) It is made from alunite. Note: It is an efficient physiological acidic fertilizer. Long-term application of sulfuric acid Potassium will increase soil acidity. In calcareous soils, it may cause soil slab. Packaging and storage and transportation: plastic woven bag packaging, transportation and storage and transportation should be moisture-proof to prevent bag damage. Category: Potassium fertilizer

ECHEMI Editorial Reference

Sodium sulfate, also known by its chemical formula Na2SO4, is an inorganic compound that is commonly encountered in the form of a white crystalline solid or as a fine powder. This substance is renowned for its high solubility in water, meaning it can easily dissolve in liquid to form a clear solution. Additionally, sodium sulfate exhibits a neutral pH level, which indicates that it is neither acidic nor basic when dissolved in water. This neutrality makes it a useful compound in various industrial and laboratory applications.
