What is sulfur used for?

Physical properties of elemental matter:

Usually a pale yellow crystal, its element name ** in Latin, originally meaning bright yellow. There are several allotropes of elemental sulfur, with rhombic sulfur (orthorhombide) and monoclinic sulfur being the most important crystalline sulfur known today. They are all made up of S8 cyclic molecules.

Density Melting point Boiling point Presence conditions.

Rhomboidal sulfur (S8) g cm3 200 or less.

Monoclinic sulfur (S8) g cm3 200 or more.

Sulfur has poor thermal and electrical conductivity. Brittle, insoluble in water, soluble in carbon disulfide (elastic sulfur can only be partially dissolved). Amorphous sulphur is mainly elastic sulphur, which is obtained by the rapid dumping of molten sulphur into ice water.

Unstable and can be transformed into crystalline sulfur (orthoclannal sulfur), which is the only form of sulfur that is stable at room temperature.

Chemical properties: Valency of -2, +2, +4 and +6. The first ionization energy electron volts.

Chemically reactive, it can be combined with oxygen, metals, hydrogen, halogens (except iodine) and most known elements. It can also react with strong oxidizing acids, salts, oxides, and concentrated strong alkali solutions. It has both positive and negative oxidation states and can form ionic compounds, covalent compounds, and coordination covalent compounds.

The important sulphide is pyrite, followed by sulphide ores of non-ferrous metal elements (Cu, Pb, Zn, etc.). Among the natural sulfates, gypsum caso4·2H2o and miscanthus Na2So4·10H2O are the most abundant. It can be made from its natural ores or compounds.

There is a lot of sulfur in the crater.

The uses of sulfur are:

1.It is used to control pests and diseases.

Sulfur is a multi-functional agent, in addition to bactericidal effect, it can also kill mites and insects. It is used to control powdery mildew and leaf mites of various crops, and the effective period can reach about half a month. The use of sulfur suspensions for vegetables is mainly used for the prevention and control of melon powdery mildew, such as cucumbers, melons (melons), pumpkins, etc., and 50% sulfur suspensions are diluted into 200-400 times liquid spray.

Spray once every 10 days or so, generally 2 times for mild onset and 3 times for severe disease.

2.To be a vulcanizing agent for radial tires.

With the development of the transportation industry, radial tires will gradually replace oblique rubber tires. As a result, insoluble sulfur is even more compelling as the main vulcanizing agent in the production of radial tires.

3.Sulfuric acid in batteries or in solution.

Sulfur is important in industry, for example as sulfuric acid in batteries or in solution. Sulfur is used in the manufacture of gunpowder, sulfuric acid, sulfites, pesticides, plastics, enamels, synthetic dyes, rubber vulcanization, bleaching, medicines, paints, sulfur ointments, etc., and is also used as a vulcanizing agent in the rubber industry.

4.Make sulfides.

Sulfuric acid is a major consumer of sulfur, with more than 70% of sulfur in China used in sulfuric acid production. Chemical fertilizer is the largest consumer of sulfuric acid, accounting for more than 70% of the total amount of sulfuric acid, especially phosphate fertilizer consumes the most sulfuric acid, and the increase is also the largest. In addition to being used in chemical fertilizers, sulfuric acid is also used to make more than 90 kinds of chemical products such as phenol and potassium sulfate.

Chemical properties of elemental sulfur:

1. Oxidation, the reaction with metal elements, often oxidizes the metal to a lower valence state. Such as sodium, potassium, silver, etc., react with sulfur to form metal sulfides. It reacts with copper and iron to form cuprous sulfide and ferrous sulfide.

2. Reducible, S reacts with a strong oxidant. Such as reaction with oxygen, reaction with concentrated nitric acid, concentrated sulfuric acid, reaction with chlorine, etc.

3. It not only shows oxidation, but also shows reduction.

Sulfur is made up of sulfur atoms. Because the substances directly composed of atoms in nature include noble gases (such as helium, neon, argon, krypton, etc.), metal elements (iron, copper, gold, mercury, etc.), solid non-metals (sulfur, silicon, carbon, etc.).

Elemental sulfur is usually a yellow crystal, also known as sulfur. There are many kinds of allotropes of sulfur element, including orthorhombic sulfur, monoclinic sulfur and elastic sulfur. The element sulfur is usually found in nature in the form of sulfides, sulfates, or elementals.

Sulfur is insoluble in water, slightly soluble in ethanol, and soluble in carbon disulfide.

Properties of elemental sulfur.

The manuscript of sulfur is very versatile.

Sulfur is mainly used to make sulfuric acid.

Sulfur is also an important raw material for the production of rubber products.

Sulfur can also be used to make black gunpowder, fireworks, matches, etc.

Sulfur is also a raw material for the manufacture of certain pesticides (e.g. lime sulfur mixture).

Medically, sulfur can also be used to make sulfur ointment to treat some ** diseases, and so on.

Sulfur is located in the 3rd period A group, the outermost shell has 6 electrons, and it is easy to obtain 2 electrons in the reaction and it is -2 valence; The highest positive price of sulfur is concession +6; The valency of elemental sulfur is 0, which is in the intermediate valence state, so elemental sulfur has both oxidizing and reducing properties, and can be used as both an oxidant and a reducing agent in the reaction.

Sulfur is a non-metallic element with the chemical symbol S and the atomic number 16. Elemental sulfur is a very common odorless and odorless non-metal, pure sulfur is a yellow crystal, also known as sulfur.

The amount of sulfur and its distribution

Sulfur is widely distributed in nature and is abundant in the earth's crust by mass). In nature, sulfur exists in the form of free states and chemical states. Elemental sulfur is mainly found in the area around the volcano.

The sulfur that exists in the chemical state is mostly minerals, which can be divided into sulfide ores and sulfate ores. Sulfide ore is cultivated with pyrite, chalcopyrite, galena, sphalerite and so on. Sulfate ores include gypsum, miscanthus, barite, lazurite, alumite, alum stone, etc.

Coal also usually contains small amounts of sulfur.

Sulfide Interpretation (1) [sulfide; sulphide] a compound of sulfur, which resembles an oxide, and with sulfur instead of oxygen (2) sulfur and an element that is usually more electropositive than it is formed by a binary compound; A salt of hydrogen sulfide (3) A compound formed by sulfur and more than one other element Word decomposition Sulfur is a non-metallic element, commonly known as "sulfur" or "sulfur", which can be used to make gunpowder, matches, pesticides, etc., and can also be used to treat diseases. radical : stone; Explanation of chemical matter

Turning into matter. It is said to be assimilated by foreign objects. "Liang Kai Li Ji - Music Record":

The touching of things is endless, and the likes and dislikes of people are unrestrained, which is the end of things and the transformation of things. Those who turn into things destroy the principles of heaven, and those who want to be poor are also. Kong Yingda Shu:

Foreign things come and go, and people are in things, good things are good to people, and things are evil to people, and people are evil, and they are human things.

Sulfur: is a non-metallic element, chemical symbol S, atomic number 16, is one of the oxygen group elements, located in the third period in the periodic table. Elemental sulfur is a yellow crystal, insoluble in water, slightly soluble in ethanol, soluble in carbon disulfide, and exists in nature in sulfide, sulfate or elemental form.

Sulfur is an important component of proteins in the human body, which is of great significance to human life activities, and is mainly used in the production of fertilizers, gunpowder, lubricants, pesticides and antifungal agents.

Sulfur refers to a chemical element. Its atomic weight is 32 and its atomic number is 16It belongs to the same family as oxygen. He has a single substance in nature, that is, sulfur, mainly in volcanic eruptions! Sulfur is a reactive non-metallic element, so I won't introduce it here.

Sulfur is a non-metallic element that occurs in numerous forms and compounds. It is widely used in many industries and also with its ions, such as sulfides and sulfides. In addition to having industrial applications, sulfur is also an important part of all living organisms, and it is also used as a food** found around some bacteria such as hydrothermal vents.
