Potassium pyrosulfate, also called potassium disulfate, is an inorganic salt that serves as a strong dehydrating and fluxing agent in chemical synthesis, particularly for dissolving minerals and for fusion analysis, known for its high melting point (around 325°C) and hazardous nature, requiring careful handling due to its corrosive properties (causes severe skin burns and eye damage)
Uses & Characteristics Fluxing Agent: Used in analytical chemistry, especially for dissolving difficult-to-dissolve substances like minerals, by fusing with them at high temperatures.
Dehydrating Agent: Its high thermal stability and ability to absorb water make it a good dehydrating agent.
Potassium pyrosulfate, or potassium disulfate, is an inorganic compound with the chemical formula K₂S₂O₇.
Potassium pyrosulfate - WikipediaPotassium pyrosulfate is used in analytical chemistry; samples are fused with potassium pyrosulfate,
CAS 7790-62-7: Potassium pyrosulfatePotassium pyrosulfate is also utilized in the production of other potassium salts and in the preparation of certain catalysts.
Hazardous: Classified as dangerous; causes severe skin burns and eye damage (H314) and can be toxic if inhaled (H331).
Safety Precautions Handling: Requires protective gear (gloves, eye protection) and should be handled in well-ventilated areas, away from moisture.
Storage: Keep in a tightly closed container in a dry place.
