Food Grade Potassium Carbonate (CAS 584-08-7)
Potassium carbonate is an inorganic substance with the chemical formula K₂CO₃, appearing as a white crystalline powder. It has a density of 2.428g/cm³, melting point of 891°C, and relative molecular weight of 138.21. Soluble in water (forming an alkaline solution) but insoluble in ethanol, acetone, and ether. Highly hygroscopic, it absorbs carbon dioxide and moisture from air, transforming into potassium bicarbonate. Requires sealed packaging to maintain stability.
