Physicochemical properties: Caustic Soda flakes is white translucent flake solid, with strong corrosive, tasted colorless transparent crystal, pure solid caustic soda were white, and a pack, flake, bar, granular, qualitative fragile, have very strong hygroscopicity. Soluble in water, dissolve exothermic, aqueous alkaline, there is a sense of satiny, Soluble in ethanol and glycerin, Insoluble in acetone, ether. With metal aluminium and zinc, and reaction with chlorine released hydrogen, such as happened was response; Halogen With acids up neutralize effect and the generated salt and water.
