What are the uses of sodium hydroxide

With the advancement of modern technology, many chemical substances are used by people. For example, sodium hydroxide is a very active chemical substance and is widely used in life, from industry to agriculture. Moreover, Qingyang exchange is also widely used in medical treatment. Let’s take a look at the detailed introduction of the uses of sodium hydroxide. I hope that those who are interested can learn more about this active chemical.

Sodium hydroxide, with the chemical formula NaOH, is commonly known as caustic soda, pyroalkali, and caustic soda. It is a strong alkali with strong corrosiveness. It is generally in the form of flakes or particles. It is easily soluble in water (releases heat when dissolved in water) and forms an alkaline solution. It is also deliquescent and easily absorbs water vapor and carbon dioxide in the air. NaOH is one of the essential chemicals in chemical laboratories and is also one of the common chemicals. The pure product is colorless and transparent crystals. Density: 2.130g/cm². 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 blocks, flakes, granules and rods. Formula weight 40.01

Physical properties: Pure sodium hydroxide is a white solid that is easily soluble in water. Its aqueous solution has an astringent taste and a greasy feel. When sodium hydroxide is exposed to the air, it easily absorbs moisture, and the surface becomes moist and gradually dissolves. This phenomenon is called deliquescence.

Uses of Sodium Hydroxide:

1. Sodium hydroxide can be used as an alkaline cleaning agent in water treatment and is soluble in ethanol and glycerol;

2. Insoluble in propanol and ether. It also corrodes sodium carbonate at high temperatures. It undergoes disproportionation reaction with halogens such as chlorine, bromine and iodine. It neutralizes with acids to produce salt and water.

3. Sodium hydroxide has a wide range of uses. In chemical experiments, in addition to being used as a reagent, it can also be used as an alkaline desiccant due to its strong hygroscopicity. Alkali is widely used in the national economy.

The above is a detailed introduction to the uses of sodium hydroxide. This is a manifestation of the progress of modern science and technology. I hope everyone can actively learn about it.
