CAUSTIC SODA FLAKESCaustic soda flakesDescription: Physical properties: white flakes, granules, shiny, color allowed, hygroscopic, soluble in water.Chemical properties: Melting point 318.4 ℃ Boiling point 1390 ℃ The relative density of 2.130Solubility: soluble in water, and strongly exothermic. Dissolved in ethanol and glycerol easily; insoluble in acetone, ether. Exposed on the air, it will eventually completely dissolved into solution. Product Name Caustic SodaMODEL NO CROWN-CS99 CAS NO1310-73-2 HS Code 2815110000EINECS NO 215-185-5,231-659-4FormularNaOHSodium hydroxide, commonly known as caustic soda, caustic soda, caustic soda. It is white crystal at room temperature, with strong corrosive. Soluble in water, its water solution is strong alkaline, can make phenolphthalein red. Sodium hydroxide is one of the most common bases and is one of the essential drugs in the chemical laboratory. Sodium hydroxide is easy to absorb water vapor in the air , must be sealed, and to use the rubber stopper. Its solution can be used as a washing liquid.
