二钠 - Introduction
Disodium is an inorganic compound with the chemical formula na2. It is a white crystalline solid that is stable at ambient temperature. Disodium has some of the following properties:
1. Solubility: Disodium has high solubility in water and can quickly dissolve into sodium ions (Na) and divalent sodium ions (Na2).
2. Alkalinity: Due to the strong alkalinity of sodium ions, Disodium can play a role in adjusting the pH.
3. Reducibility: Disodium has strong reducibility and can be used as a reducing agent in some chemical reactions.
Disodium has a variety of uses in many areas:
1. Chemical Laboratory: used as reagents and standards.
2. Chemical industry: used to prepare other compounds, such as sodium hydroxide, sodium carbonate, etc.
3. Metal processing: used to remove the oxide on the metal surface.
4. Glass industry: As one of the components of glass products, it can adjust the refractive index and melting point of glass.
Common methods of preparing Disodium include:
1. By reaction: sodium is reacted with tartaric acid solution to obtain Disodium tartrate, and then tartaric acid group is removed by reaction with sodium hydroxide to obtain pure Disodium.
2. Electrolysis method: pure Disodium can be obtained by electrolysis of saturated sodium chloride solution.
It should be noted that Disodium is a strong reducing agent. When it comes into contact with water and moisture, it will react violently to produce hydrogen, which can easily cause fire or explosion. In addition, Disodium is also corrosive to the skin and eyes, so protective measures should be worn when using it. When storing and using, it should be kept in a sealed container, away from fire and flammable materials. If necessary, professionals should be invited to operate.
