Caustic Soda, also named sodium hydroxide, NaOH, is caustic alkali with strong causticity, generally presented as flake or pearl form, soluble in water, soluble in water heating and formation of alkaline solution, otherwise deliquescence, easy to absorb water vapor in the air.NaOH is one of the essential chemicals in the chemistry laboratory. It is also one of the common chemicals. A pure product is a clear, colorless crystal.

Industrial sheet alkali contains a small amount of sodium chloride and sodium carbonate. It is a white opaque crystal with lumpy, flake, granular and rod shapes.

Formula 40.01 sodium hydroxide can be used as basic cleaning agent in water treatment, soluble in ethanol and glycerol.Insoluble in propyl alcohol and ether.It can also corrode sodium and carbon at high temperature.

And chlorine, bromine, iodine and other halogens undergo disproportional reaction.

Neutralize with acids to form salts and water.
