Potassium Sulfite Lab Grade

Potassium Sulfite, also known as Dipotassium Sulfite, and Sulfurous Acid-Dipotassium salt, has the chemical formula K₂O₃S or K₂SO₃ . It appears as white to white-yellowish crystalline hygroscopic powder with no odor. Potassium Sulfite can undergo decomposition by diluted acids with the evolution of Sulfur Dioxide. It is slightly soluble in Water and Alkaline solutions at ambient conditions. Commonly, Potassium Sulfite is prepared by the absorption of Sulfur Dioxide gas in Potassium Carbonate or Potassium Hydroxide. Chemically pure or Laboratory reagents are the two terms often used to describe Lab Grade chemicals. Lab Grade chemicals do not meet any accepted quality or purity requirements such as the ACS Grade, the USP Grade, and the FCC Grade, despite their acceptable purity. In the United States of America (USA), Lab Alley is selling its high-quality Potassium Sulfite, Lab Grade online at laballey.com. Due to its high purity, Lab Alley’s Potassium Sulfite, Lab Grade is highly recommended for labs and commercial applications.
