Explanation Oxidizing Oxides Oxidants 15

Oxides are a genus of substances: Oxides are one of the compounds. Compounds made up of oxygen and another element are called oxides. There are only two elements in the composition, one of which is oxygen.

According to the different oxides of the element, they can be divided into metal oxides and non-metal oxides. According to the different properties, it can be divided into acidic oxides. Basic oxides. Amphoteric oxides and neutral oxides (not salt oxides).

Oxidation is a property of matter. In chemical reactions, other substances can be oxidized. The atoms of the elements contained in the substance have a relatively strong ability to bind electrons, and the electrons of other atoms can be seized in the reaction, so that the valency of other elements increases, then the substance shows oxidation.

Oxidants are reactants that are oxidizing in chemical reactions.

Oxides are classified from the classification of substances, pure substances are divided into elemental substances and compounds, and oxides are one of the compounds, which are defined as the products of oxidation reactions. It can only be composed of two elements, and one of them is oxygen. According to the types of constituent elements, they can be divided into non-metallic oxides, such as CO2 and H2O, and metal oxides, such as Cuo and Cao

Oxidant is a substance that plays an oxidizing role in redox reactions. It is manifested as the acquisition of electrons, and the valency of an element in the substance decreases.

Oxidation is a chemical property that refers to the role that an oxidizing agent plays in a chemical change.

Oxide refers to a compound containing the element oxygen, and if memory serves, it is required to be composed of only two elements, one is oxygen.

Oxidant is a reactant in a redox reaction in which the valency of an element decreases.

Oxides, which are binary compounds composed of negative valence oxygen and another chemical element, such as iron oxide or alumina, are usually produced by oxidation. Oxides are extremely ubiquitous in the Earth's crust, but also in the solids of the universe.

Oxygen ions are conjugate bases of hydroxide ions and are present in certain oxide ion crystals. Free oxygen ions are strongly alkaline and unstable in aqueous solutions.

The oxygen element in the oxide should be in a negative oxidation state. If the oxygen in an oxygenated binary compound, such as dioxygen difluoride and oxygen difluoride, is in a positive oxidizing state, they are generally referred to as fluoride rather than oxides.

Oxides are made up of two elements, one of which is oxygen.

compounds. Substances that can react with oxygen are called oxides. Depending on their chemical properties, oxides can be classified as acidic oxides.

1. Classification of oxidants.

According to the medium required by the oxidation reaction, it is divided into the following three categories: acidic medium oxidant (hydrogen peroxide, peracetic acid, sodium dichromate, chromic acid, nitric acid, potassium permanganate, ammonium persulfate);Alkaline medium oxidant (sodium hypochlorite, sodium percarbonate, sodium perborate, potassium perborate);Neutral oxidants (bromine, iodine).

According to its danger, it is divided into primary oxidant and secondary oxidant;Oxidants are divided into inorganic oxidants and organic oxidants according to their chemical composition.

2. Common stupid oxidants.

Typical non-metallic elements such as F2, Cl2, O2, Br2, I2, S, Si, etc. (the oxidation strength is basically the same as that of non-metallic activity); ** compounds containing valence elements, such as KMno4, KCLO3, concentrated H2SO4, HNO3, MNO2, FeCl3, etc.; Metal cations such as: Fe3+, Cu2+, etc.

Application and storage of oxidants:

1. Application. In the chemical industry, it is widely used in the production of a variety of raw materials and finished products. Oxidants are commonly used in metallurgy to remove impurities and purify the smelted metals, such as iron ore, iron phosphorus, air or industrial pure oxygen used in the steelmaking process.

In chemical batteries, oxidants are commonly used to remove oxygen from the positive electrode, called "removers", such as manganese dioxide used in dry batteries.

2. Storage. In addition to non-flammable and disturbing branch burning gases, they shall not be stored together with other articles that conflict with each other; Different varieties of oxidants should be stored in separate stacks, and it is strictly forbidden to mix with organic combustibles. Before and after storage in the warehouse, it should be thoroughly cleaned to prevent impurities from being mixed; Friction and impact should be avoided during storage.

You can refer to ** items.

The packaging should be intact and tightly tied without spillage to avoid danger. In case of damage to the packaging, measures should be taken immediately, and the leakage part should be thoroughly scanned and sensitized; The warehouse shall not leak water, and shall prevent the invasion of acid mist, etc., and it is strictly forbidden to mix with acids. The warehouse should be cool and ventilated to prevent sunlight exposure.

1. Oxidation refers to the ability of a substance to obtain electrons. Substances in the ** state and active non-metallic elements (such as fluorine, chlorine, oxygen, etc.) are generally oxidizing, while substances in the low-valence state are generally reducible.

2. The strength of oxidation can generally be judged according to the following methods:

1) For metal oxidants, the oxidation strength of metal cations is generally opposite to the order of metal activity, that is, the more metal in the back, the easier it is to obtain electrons, and the stronger the oxidation.

2) Order of oxidation of metal cations (25, pH = 1 in aqueous solution).

1. Oxidation refers to the ability of a substance to obtain electrons. Substances in the ** state and active non-metallic single-bond wax (such as fluorine, chlorine, oxygen, etc.) generally have oxidizing properties, while substances in the low-price state generally have reducing properties.

2. The ability of a substance to obtain electrons in a chemical reaction.

Substances in the ** state are generally oxidizing, such as: some non-metallic elements: O2, Cl2; Part** metals: Fe3+, MnO4- etc.

Substances in the low-valent state are generally reducible (e.g., some metal elements (in middle school, metal elements are only reducing, in fact, negative valence metals are very common), some non-metal anions: br-, i-, etc.

Substances in the intermediate valence state are generally both reducing and oxidizing (e.g., tetravalent sulfur).

OxidationRefers to the ability of a substance to obtain electrons. Substances in the ** state and active non-metallic elements (such as: fluorine, chlorine, oxygen, etc.) generally have oxidizing properties, while substances in the low-price state generally haveReductiveness

Generally speaking, valence elements are only oxidized when they are in the most ** state, only reducing when they are in the lowest valence state, and both oxidizing and reducing when they are in the intermediate valence state. Generally, when it is in the most ** state, the oxidation is the strongest, with the valency.

Decreased, oxidation weakened, and reductive increased. However, there are also counter-examples, for example, in acidic aqueous solution, from 0 to the most, the oxidation of chlorsulfion and phosphorus increases with the decrease of valence.

Oxidizing substances:

An oxidizing substance is a chemical property that may not be burned by itself, but can release oxygen, which may cause or promote the combustion of other substances.

Comparatively reactive substance. It often refers to the atomic structure containing ** state in inorganic compounds.

and substances containing a dioxygen structure. It generally does not burn on its own.

However, if it encounters acid or is exposed to moisture, strong heat, or contact with other reducing substances and flammable substances, it can carry out oxidative decomposition reaction, release heat and oxygen, cause the combustion of combustible substances, and sometimes form a first-class mixture. The International Maritime Dangerous Goods Code classifies oxidizing substances as Class I dangerous goods. Oxidation reactions.

There are oxidants and reducing agents in the reduction reaction.

The above content refers to: Encyclopedia - Oxygen Calendar Chemical Resistance.

Oxidant is a substance that obtains electrons or has electron pair bias in the redox reaction, that is, it changes from ** to low price. The oxidant gets its electrons from the reducing agent and the electrons are reduced to the reducing products themselves. Oxidants and reducing agents are interdependent.

Common oxidizing agent.

Common oxidants are substances that are easily reduced in chemical reactions. (1) Typical non-metallic elements such as F2, O2, Cl2, Br2, I2, S, etc. (their oxidation is basically the same as that of non-metallic activity). 2) ** compounds containing valence elements, such as KMno4, KCLO3, concentrated H2SO4, HNO3, MNO2, FeCl3, etc.

3) Metal cations such as: Fe3+, Cu2+, (H+) (in the displacement reaction of metal with acid and salt solution, such as the reaction Fe CuSO4=Feso4 Cu, it is essentially Cu2+ ions oxidizing Fe atoms, Cu2+ as oxidizing agent, and Fe as reducing agent).

Oxidants include inorganic oxidants and organic oxidants, acidic medium oxidants, alkaline medium oxidants, and neutral oxidants.

Oxidants are divided into inorganic oxidants and organic oxidants according to their chemical composition. It can also be divided into 3 categories according to the medium required for the oxidation reaction: acidic medium oxidation agent (e.g.

Hydrogen peroxide, peracetic acid, sodium dichromate, chromic acid, nitric acid, potassium permanganate, ammonium persulfate). Alkaline medium oxidants (e.g., sodium hypochlorite, sodium percarbonate, sodium perborate, potassium perborate).

Neutral oxidants (e.g., bromine, iodine).

Oxidant chemistry

The electron-gaining property of an oxidizing agent is called oxidation, and the determining factor of oxidation is the electron-gaining tendency of the ** state element in the substance. In solution, according to the electric double-layer theory, the magnitude of oxidation is reflected as the standard hydrogen electrode potential of the oxidant: the higher the potential, the stronger the oxidation; The lower the electric potential, the weaker the oxidation, and correspondingly, the stronger the reduction of the reduced state.

In water, most of the oxidizing reactions of oxidants are divided into three steps: dissociation, affinity, and synthesis. These three steps determine the enthalpy of the oxidation reaction and have a great impact on the oxidation of the oxidant.

Hydrogen ions also play a very important role in the oxidation modification of oxygen-containing oxidants, because hydrogen ions have a very large reverse polarization capacity, making the X-O bond unstable (X refers to the central atom of the oxidant). Therefore, in general, under acidic conditions, the oxidizing agent is more oxidizing than when it is alkaline. For some species that are not affected by hydrogen ions, such as Cl2, Br2, etc., their oxidation is independent of pH.

In addition, the oxidation of the oxidant is also affected by the symmetry of the molecule, the more symmetrical the molecule is, the more stable it is, such as perchloric acid completely ionized in water, its symmetry is quite good, so that the oxidation of perchlorate in water is not very strong. Therefore, for non-metallic oxygenated acids, the oxidation of the ** state is generally not as good as that of the low-price state.
