Anonymous users2024-02-09All the chemical equations for sodium and its compounds are:1. Sodium and oxygen reaction at room temperature: 4Na+O2=2Na2O.
2. Sodium and oxygen ignition condition reaction: 2Na+O2=Na2O2 (ignition).
3. Sodium and water reaction: 2Na + 2H2O = 2NaOH + H2.
4. Reaction between sodium and sulfuric acid: 2Na + H2SO4 = Na2SO4 + H2.
5. Sodium oxide reacts with water: Na2O+H2O=2NaOH.
6. Reaction between sodium peroxide and carbon dioxide: 2Na2O2+2CO2=2Na2CO3+O2.
Industrial Uses of Sodium:Determination of chlorine in organic matter. Reduced and hydrogenated organic compounds. Detection of nitrogen, sulfur and fluorine in organic matter.
Removal of water from organic solvents (benzene, hydrocarbons, ethers). Impurities such as oxygen, iodine or hydroiodic acid are removed from hydrocarbons. Preparation of sodium amalgamation, sodium alkoxide, pure sodium hydroxide, sodium peroxide, sodium amino, alloy, sodium lamp, photocell, and active metal.

Anonymous users2024-02-08The chemical formula of sodium is Na.
Sodium in the periodic table.
It is located in the 3rd period, group a, is a representative of alkali metal elements, has a soft texture, and can react with water to form sodium hydroxide.
Hydrogen is released, and the chemical properties are more active. Elemental sodium.
Widely distributed in the form of salt on land and in the sea, sodium is also one of the important components in human muscle tissue and nerve tissue.
A total of 22 isotopes of sodium have been discovered, ranging from sodium-18 to sodium-37, of which only sodium-23 is stable and the other isotopes are radioactive.
Chemical properties of sodium
The outermost shell of the sodium atom has only 1 electron and is easily lost, so it is strongly reducible. Therefore, the chemical properties of sodium are very active, and it can react with a large number of inorganic substances, most non-metallic elemental substances and most organic substances;
In redox with other substances.
When reacting, as a reducing agent, it is all from 0 valence to +1 valence (due to NS1 electron pairs), usually combined in the form of ionic bonds and covalent bonds. The metallicity is strong, and its ionic oxidation is weak. The relative atomic mass of sodium is.
