caustic soda
Alkali is also known as sodium hydroxide.
Sodium hydroxide, with the chemical formula NaOH, commonly known as caustic soda, caustic soda, or caustic soda, is a highly corrosive strong alkali that is generally in the form of flakes or blocks. It is easily soluble in water (releases heat when dissolved in water) and forms an alkaline solution. It also has deliquescence and can easily absorb water vapor (deliquescence) and carbon dioxide (deterioration) from the air. It can be tested for deterioration by adding hydrochloric acid.
NaOH is one of the chemicals used in chemical laboratories and is also a common chemical product. Pure product is a colorless and transparent crystal. Density 2.130g/cm3. Melting point 318.4 ℃. Boiling point 1390 ℃. Industrial products contain small amounts of sodium chloride and sodium carbonate, which are white opaque crystals. There are block shaped, flake shaped, granular, and rod-shaped forms. Equation quantity 39.997.
Sodium hydroxide can be used as an alkaline cleaning agent in water treatment, soluble in ethanol and glycerol; Insoluble in propanol and ether. Disputation reaction occurs with halogens such as chlorine, bromine, iodine, etc. Neutralizes with acids to produce salts and water.
