2. Physicochemical Properties

Appearance: Pure grade – white/light yellow cubic crystalline solid; industrial grade – reddish-brown, yellow flake/block
Density (25°C): 1.86 g/cm³
Melting Point: 950 °C
Solubility: Highly soluble in water, dissolves to form strongly alkaline solution (pH＞13); slightly soluble in methanol/ethanol, insoluble in ether
Hygroscopy: Extremely deliquescent; rapidly absorbs water & CO₂ from air
Air Stability: Oxidizes on exposure to air, generates hydrogen sulfide (toxic rotten egg odor), sodium thiosulfate & sodium carbonate impurities
