Can anyone give me a detailed explanation of the redox reaction?

Chemical reaction: Reducing agent (reactant) Loss of electrons or deviation of shared electron pairs Increased valency Oxidation Occurrence of oxidation reaction Formation of oxidation products Reduction reaction: Oxidant (reactant) Electrons or shared electron pairs bias Decreased valency Reduced Reduction reaction Occurrence of reduction reaction Formation of reducing products The specific laws of redox reactions are:

1 Equilibrium law: In redox reactions, the total number of electrons gained and lost is equal, and the valence rises and falls in total value 2 Strength and weakness law: satisfied in the reaction:

Oxidation: Oxidant >> Oxidation Product Reducibility: Reducing Agent >> Reducing Product 3 Valence Law:

The element is in the most advanced state and only has oxidizing properties; The element is in the lowest valence state and is only reductive; It is in the intermediate valence state, which is both oxidizing and reducing. 4 Transformation law: When the centering reaction occurs between different valence states of the same element, the valency of the element is only close but not crossed, and at most it can only reach the same valence state 5 priority law:

In the same redox reaction, when the oxidant encounters multiple reducing agents, it reacts with the strongest reducing agent first.

Redox reaction, as the name suggests, is the reaction between the oxidant and the reducing agent, in which the reducing agent loses electrons, and the lost electrons are all taken away by the oxidant, some elements tend to lose electrons, and some elements tend to get electrons, so in this case, a redox reaction will occur, the redox reaction is a dozen chemical reactions, which can be designed as galvanic batteries, and the batteries we usually use are also produced according to the redox principle.

Redox antiparenchyma is the movement of electrons.

There is a regular satisfaction.

1. In the redox reaction, the total number of electrons gained and lost is equal, and the valence rises and falls in the total value of the balance 2 in the reaction: oxidation: oxidant, oxidant, oxidation product, reducibility:

The 3 elements of the reducing product are in the most advanced state and only have oxidation; The element is in the lowest valence state and is only reductive; It is in the intermediate valence state, which is both oxidizing and reducing.

4. When the centering reaction occurs between different valence states of the same element, the valency of the element is only close but not crossed, and can only reach the same valence state at most 5. In the same redox reaction, when the oxidant encounters a variety of reducing agents, it reacts with the strongest reducing agent first.

In response, it can be by.

valency) rise and loss (electron) oxidation (reaction) reducing agent.

valency) to reduce (electron) to the oxidant.

Determine reducing agents and oxidants.

and oxides and reductions.

The reaction in which the valency of a substance increases is called an oxidation reaction.

A reaction with a decrease in the valency of a substance is called a reduction reaction.

A reaction with electron gain, loss, or shift is called a redox reaction.

The valence is conserved in rise and fall.

Conservation of electron gains and losses.

c+o2=co2

Carbon is oxidized) CuO+H2=Cu+H2O (copper oxide is reduced).

Redox reactions usually occur together, i.e., there is oxidation and reduction at the same time. When a reaction is carried out, there is a valency rise and fall in the redox reaction. i.e. the movement of electrons.

For example, C and O2 react to form CO2, in this reaction, the carbon atom changes from 0 valence to +4 valence, that is, he loses four electrons, then the carbon atom is called the reducing agent, it undergoes an oxidation reaction, and the oxygen atom changes from 0 valence to -2 valence, that is, 2 electrons are obtained, he is the oxidant, and the reduction reaction occurs. But there are also special cases, such as disproportionation reaction, which refers to a molecule that acts as both an oxidant and a reducing agent, that is, the valence rises and falls, and the law is that the oxidant and the reducing agent react, strong oxidation and strong reducing reaction, or weak and weak. I won't give any examples.

All displacements, and most of the decomposition, compounding.

If the valency of an atom rises in the reaction, it is said that the atom has an oxidation reaction, and vice versa, it is a reduction reaction, and the reaction in which the atom in the reaction has a change in valency is called a redox reaction, and the valency of another atom must be reduced by 2FeCl2 + Cl2 = 2FeCl3

2FeCl3, 2Hi, 2FeCl2, 2HCl, I2, etc.

A redox reaction is a chemical reaction in which the valency of an element changes before and after the reaction. This reaction can be understood as consisting of two halves, namely oxidation and reduction.

Note: None of the metathesis reactions are redox reactions.

Most of the chemical reactions with the participation of elemental elements are redox reactions (with the exception of graphite turning into diamond under certain conditions, and also includes the conversion between other allotropes). ）

Most of the decomposition reactions with elemental formation are redox reactions (with the exception of hypofluoric acid decomposition: 2HF==2HF+O2, and the valency does not change).

The centering reaction, the disproportionation reaction can be regarded as a special redox reaction.

Be. Redox reactions.

It should be FE from 0 to +2.

CU has been reduced from +2 to 0.

According to the basic concept of redox: in the non-imitation beam machine reaction, there is a chemical reaction in which the valence of the elements rises and falls, that is, the electron transfer and preparation (gain or loss or offset) is a redox reaction.

There is another pattern.

The reaction above.

It's a dot type.

Alternating the state of the rubber reaction.

All displacement reactions are redox reactions.

Because it will be accompanied by the rise and fall of valency and the transfer of electrons!!

You should get the idea.

Be. The essence of the oxidation and rotten slipperone reaction is the gain and loss of electrons. Iron and copper sulfate react to form iron sulfate and copper, and Fe changes from 0 valence to +2 valence. CU changes from +2 valence to 0 valence, which is in line with the essence of the oxo-cracking historical potato reduction reaction. So iron.

The reaction with copper sulfate is a redox reaction.

By the way, all displacement reactions are redox reactions, you just remember.

Similar to the reaction between iron and copper sulfate, this is the displacement reaction.

Chemistry class representative, ah ......

Redox reaction, literally, refers to the reaction of one substance being oxidized and another substance being reduced, in fact, as long as the reactants are chemical reflexes in the reaction, they should all belong to the oxonium rising and reducing reaction, such as the reaction of chlorine and elemental sodium to produce sodium chloride is a redox reaction. In the redox reaction, the substances with increased valency are oxidized and are reducing agents; Substances with reduced valency are reduced and are oxidizing agents.

Above, if there is anything you don't understand, continue to ask

You can write both reactions as ionic reactions, and the equations are both.

2 (Fe3+) + 2 (I-) = I2 + 2Fe2 + is the machine rotten and the cavity is the ferric ion of the iodine ion, the iodine ion oxidation of the hunger shirt into the iodine element, and the jujube is reduced to the divalent iron ion.

According to the reductive I-Fe2+

So the reaction can be carried out.

The number of electrons in this reaction is transferred to 4 electrostools.
