Industrial grade:GB/T209-2018
Sodium hydroxide, chemical formula is NaOH, commonly known as caustic soda, caustic soda, caustic soda, when dissolved, emits ammonia taste, is a highly corrosive strong alkali, generally in sheet or particle form, easy to dissolve in water (heat release when dissolved in water) and form alkaline solution, and delixability, easy to absorb water vapor in the air (delixation) and carbon dioxide (metamorphism). NaOH is one of the necessary chemicals in chemical laboratories and one of the common chemicals. Pure products are colorless and transparent crystals. Density 2.130g/cm³. Melting point 318.4ºC. Boiling point 1390ºC. Industrial products contain small amounts of sodium chloride and sodium carbonate, which are white opaque crystals. There are lumps, sheets, granules and rods. The equation is 40.01
Sodium hydroxide can be used as alkaline cleaning agent in water treatment, soluble in ethanol and glycerol; Insoluble in propanol and ether. It also has a corrosive effect on sodium carbon at high temperature. Disproportionation reaction with chlorine, bromine, iodine and other halogen. Neutralizes with acids to produce salt and water.
PACKAGE:25kg bag,customized package;1 - 1.2 tons pallets customized package accepted.
Caustic soda is one of the must-have chemical which is used in many industries. We have our own factory of caustic soda and we are the professional caustic soda
suppliers in China. Making sure good quality and fast shipment.
Caustic soda ( sodium hydroxide) is a soluble strong base. Caustic soda is widely used in: Bleach - Bleach for industrial, industrial and consumer applications.
Petroleum Products - used in the exploration, production and processing of oil and gas. Aluminum production - used to dissolve bauxite, the raw material for aluminum production.
Chemical Processing - used as a basic raw material for a wide range of downstream products including solvents, plastics, fabrics, adhesives, paints, herbicides, dyes, inks, pharmaceuticals, etc.
Cleaning supplies such as water treatment and sewage and pipeline cleaning agents
Other small-scale applications of caustic soda include bottle cleaners, oven cleaners, and other household cleaning products, as well as household soap.
Sodium hydroxide dissolved in water will completely dissociate into sodium ions and hydroxide ions, so it has the universality of alkali.
It can undergo acid-base neutralization reaction (also a metadecomposition reaction) with any protic acid:
NaOH + HCl = NaCl + H2O
2NaOH + H2SO4=Na2SO4+2H2O
NaOH + HNO3=NaNO3+H2O
Similarly, its solution can undergo metadecomposition reaction with salt solution:
NaOH + NH4Cl = NaCl +NH3·H2O
2NaOH + CuSO4= Cu(OH)2↓+ Na2SO4
2NaOH+MgCl2= 2NaCl+Mg(OH)2↓
