1. Sodium hydroxide, chemical formula NaOH, commonly known as caustic soda, caustic soda, caustic soda. It is a strong base, usually in the form of flakes or blocks. It is easily soluble in water (releasing heat when dissolved in water) and forms an alkaline solution. It is also prone to deliquescence, easily absorbing water vapor (deliquescence) and carbon dioxide (spoilage) from the air. You can add hydrochloric acid to check if it has deteriorated.
2.NaOH is one of the commonly used chemical drugs in chemical laboratories. The pure product is a colorless transparent crystal. Density 2.130g/cm, melting point 318.4, boiling point 1390. Industrial products contain small amounts of sodium chloride and sodium carbonate, and are white opaque crystals. There are block shaped, flake shaped, granular, and rod-shaped. The number of models is 39.997.
3. Soda flakes can be used as alkaline cleaning agents in water treatment, soluble in ethanol and glycerol; Insoluble in propanol and ether. Disputation reaction with halogens such as chlorine, bromine, iodine, etc. It reacts with acid to neutralize and form salt and water.
