What are oxidizing and reducing? What are oxidizing and reducing properties?

Oxidity is the property of the element or substance that has electrons and reduced chemical bonds.

Reducibility is the property of an element or substance that loses electrons and elevates chemical bonds.

As; 2 h2+o2=2 h2o

H2 loses electrons, chemical bonds are elevated, and it is reducible.

O2 gets electrons, the chemical bonds are reduced, and it is oxidizing.

To put it simply, oxidation refers to the ability of a substance to gain electrons, and correspondingly, reductivity refers to the ability of a substance to lose electrons.

The property of a substance giving (losing) electrons is known as reducibility, and a reducing agent is the donor of electrons. The property of a substance that accepts (gets) electrons is called oxidation, and the oxidizing agent is the acceptor of electrons.

The strength of the oxidation or reduction of a substance is determined by the difficulty of gaining and losing electrons, and has nothing to do with the number of electrons gained or lost. 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.

To compare the oxidation or reduction of different substances, there are mainly the following methods:

1. Compare the conditions required and the intensity of the reaction between different oxidation catalysts (or reducing agents) and the same reducing agent (or oxidant).

For example, sodium reacts violently with water at room temperature to form hydrogen, magnesium does not react easily with cold wheel water, and hydrogen can also be generated when heated, but slowly, indicating that sodium is more reducible than magnesium.

2. The principle of "strong forcing weak and weak", that is, the stronger oxidant and the reducing agent react to generate the weaker oxidant and reducing agent.

Oxidation refers to the ability of a substance to gain electrons, and reducibility refers to the ability of atoms, molecules, or ions to lose electrons in a chemical reaction.

A method for judging the oxidation of different substances formed by the same element and the strength of the reduction.

1. Judge according to the valency of the elements.

The most ** only has oxygen nucleation corruption, the lowest valence is only reducing, and the intermediate valence has both oxidation and reducibility.

2. Judge according to the concentration of the substance.

The greater the concentration of an oxidizing (or reducing) substance, the stronger its oxidizing (or reducing) and vice versa.

Methods for judging the oxidation of different substances or different elements, and the strength of reduction:

1. Judging according to the chemical equation.

Oxidation: Oxidation products.

Reducibility: Reduced product.

2. Compare according to the order of material activity.

For metal reducing agents, the reducibility of metal elements is generally consistent with the order of metal activity.

For metal oxidation, the order of metal cation oxidation is the opposite of the order of metal cation oxidation.

3. Comparison of the acidity and alkalinity of hydrates according to the most ** oxides of the elements.

The more acidic it is, the more oxidizing the corresponding element is.

The stronger the alkalinity, the stronger the reduction of the corresponding element<>

Oxidity and reducibility are descriptions of the electrical capacity of a substance.

1. Oxidation refers to the ability of substances to obtain electrons, and common substances in the ** state and active non-metallic elements generally have oxidation.

2. Reducibility refers to the ability of atoms, molecules or ions to lose electrons in chemical reactions.
