Caustic Soda Solid CAS No.1310-73-2 purity: 98% Flakes

Sodium hydroxide, with the chemical formula NaOH, is commonly known as caustic soda. It is a strong alkali with strong corrosivity, generally in the form of flakes or granules. Alkaline solution is also deliquescent, easy to absorb water vapor (deliquescent) and carbon dioxide (deterioration) in the air. NaOH is one of the necessary chemicals in the chemical laboratory, and it is also one of the common chemicals. Pure products are colorless and transparent crystals. The density is 2.130g / cm ?. Melting point 318.4 ° C. The boiling point is 1390 ° C. The industrial product contains a small amount of sodium chloride and sodium carbonate, and is a white opaque crystal. There are lumps, flakes, grains and rods. Formula 40.01 Sodium hydroxide can be used as alkaline cleaning agent in water treatment, soluble in ethanol and glycerin, but insoluble in propanol and ether. It also has a corrosive effect on sodium carbonate at high temperatures. Disproportionation with halogens such as chlorine, bromine and iodine, and neutralization with acids to form salts and water
