Sodium, a metallic element with a soft texture, splits water to release hydrogen. The content of sodium 1 in the earth's crust ranks sixth, mainly in the form of sodium salts, such as table salt (sodium chloride), Chilean saltpeter (sodium nitrate), soda ash (sodium carbonate), etc. Sodium is also one of the main components in the body's muscle and nerve tissue.
Silvery-white cube structure metal. The new facet glows and oxidizes in the air to a dull gray. Soft and light, it hardens at -20, reacts violently with water, generates sodium hydroxide and hydrogen gas, and produces a large amount of heat and spontaneously ignibrates or **.
In the air, it glows with a yellow flame when burning. It will also react with ethanol and react with the hydroxyl group of ethanol to produce hydrogen and sodium ethanol, and release heat at the same time. It can be directly combined with halogens and phosphorus.
It can reduce many oxides into an elemental state, and can also reduce metal chlorides. When dissolved in liquid ammonia, it becomes a blue solution. Sodium amino is formed by heating in ammonia.
Soluble in mercury to produce sodium amalgamation. Relative density (H2O). Melting point.
Boiling point. Corrosive. A small amount is immersed in kerosene or mineral oil that does not contain free oxygen and moisture and is sealed and preserved, and a large amount is usually stored in iron drums for sealed preservation Safety measures Store in a cool and dry place, away from fire and heat sources.
It is stored separately with oxidants, acids and halogens. Fire extinguishing: graphite powder, sodium carbonate dry powder, calcium carbonate dry powder.
It is forbidden to extinguish fires with water and chlorinated hydrocarbons.

Sodium metal is classified as a dangerous good.
Danger: easy to spontaneous combustion, heat release in contact with water.
Control Type: Easy to Explosive.
Chemical properties: The chemical properties of sodium are very reactive, and they are heated at room temperature and at normal temperature.
The properties of sodium metal: when it is combined with oxygen, it reacts violently with water, and occurs when the amount is large**. Sodium can also be burned in carbon dioxide, react with low-element alcohols to produce hydrogen, and react with liquid ammonia, which has a weak ionization capacity.

Sodium is a dangerous good.
Sodium is a chemical element with the chemical symbol Na and its atomic number 11. Sodium elemental matter does not exist in the earth's nature because sodium oxidizes rapidly in the air and reacts violently with water, so it can only be found in chemical compounds.

Sodium is a dangerous good.
Specifically, sodium, CAS number: 7440-23-5, UN number: 1428, dangerous goods class:
It belongs to the class of dangerous goods - substances that emit flammable gases when exposed to water. I am a professional in the import and export of dangerous goods, with many years of experience in the import and export of dangerous goods, if you have other questions, you can also come to me at any time.

It has strong oxidation under acidic conditions, and neutral and alkaline can almost ignore this thing.
-
Sodium nitrate is a strong oxidizing agent and corrosive.
-
It is a dangerous good.
Sodium is a metallic element that is located in the 3rd period, group a, in the periodic table, and is a representative of alkali metal elements with a soft textureIt can react with water to generate sodium hydroxide and release hydrogen, which occurs when the amount is large, and the chemical properties are more active.

Isn't that good! We've been waiting for it all these years.
Some. Acetylene is the simplest alkyne, also known as calcium carbide gas. The molecular formula CH, the chemical formula CH. >>>More
Common dilution methods of acid and alkali solution include direct water soluble method, medium water soluble method, and dilution method. 1. The direct water solubilization method accurately weighs the reference substance, and the fixed volume becomes the standard solution of accurate concentration after dissolution. For example, when it is necessary to prepare 500ml of mol·l-1 K2Cr2O7 solution, the reference substance K2Cr2O7 should be accurately weighed on the analytical balance, dissolved by adding a small amount of water, quantitatively transferred to a 500ml volumetric flask, and diluted to the scale with water.
Your own makeup remover is certainly not corrosive, because I have been using this cleansing water for many years and have never found anything unsuitable. And the makeup removal effect is very good, and it can also achieve the effect of cleansing and clearing the skin, so I am quite relieved that my makeup remover is still very reassuring.
The adhesive remover is toxic, but as long as it is not a large number of long-term contact, it will not have much impact on the body, if you must contact the use, please try to wear masks and gloves, if you feel uncomfortable, please go to the ventilated environment in time to move, breathe fresh air, can be relieved!
English: oxide – oxide
According to different chemical properties, oxides can be divided into two categories: acidic oxides and basic oxides. >>>More
