The electrolyte solution conducts electricity because of what is present

Metal conduction and electrolyte solution conduction are two different ways of conducting electricity.

Metals conduct electricity because there are free electrons in the metal, and the directional movement of free electrons makes the metal conductive;

The electrolyte solution conducts electricity because there are freely moving ions in the electrolyte solution, and the directional movement of the ions makes the electrolyte solution conductive.

In a nutshell, one is electronically conductive and the other is ionic.

There are anion and ions that move freely.

There are freely moving anions and cations, which are ionized out of the solute in solution.

Anions and cations, which can move freely, move directionally under the action of an external electric field, and redox reactions occur at the poles.

First of allElectrolyte solutionConduction is a physical reaction because it is just the directional motion of ions.

Secondly, the electrolysis of any electrolyte such as NaCl, MgCl2 is a physical change because no new species are formed.

Because solid NaCl actually has sodium ions.

and chloride ion group segments, there is no such thing as a sodium chloride molecule. After electrolysis, sodium ions and chloride ions are still present in the solution.

And the total amount of ions does not change, which also implies that it is a physical reaction. Salt water is a mixture of table salt and water, and the mixture cannot be called an electrolyte. The main electrolyte is NACL in table salt.

If you want to add a small amount of AgNO3 to the salt water, then it is a chemical change, because the Ag+ and Cl- ions form a precipitate.

Moreover, the amount of Cl- ions in the original solution is reduced, because the precipitated AGCL will not be ionized into AG and Cl ions, which is more certain that the formation of the precipitate is a chemical change.

In the process of conducting electricity, it is accompanied by chemical reactions.

A redox reaction occurs on the cathode and anode.

For example, a sodium chloride solution.

Energized, under the action of the electric field, chloride ions move towards the anode, sodium ions move towards the cathode, and chloride ions lose electrons on the anode.

The reaction produces chlorine gas.

Although sodium ions accumulate at the cathode, it is not it that gets electrons, but H+, and the reaction becomes hydrogen. Finally, there will be a large number of large hydroxide excitons near the cathode.

The electrolyte solution conducts electricity, which is a physical change, not a chemical change. Chemical change, from the point of view of junior high school, is whether or not a new substance is produced. When I entered a new layer of high school, the criterion for judging was whether there was a break of the old bond and the formation of a new one.

Therefore, from the perspective of this filial piety standard, it is obvious that it is not a change in the study of empty space.

The electrolyte solution conducts electricity because it can ionize anions and cations in an aqueous solution, so it is a chemical change.

The electrolyte solution conducts electricity and is a physical change. Acting like a conductor conducts electricity, there are freely moving electrons. The electrolyte solution conducts electricity because there are freely moving ions in the solution when it is not rented. There is no new substance in this process, so it is a physical change.

No, the conduction of an electrolyte solution is a physical change. It is only a directional movement of the ions of the electrolyte, but there is no material change of the excitation on the essence of the Ming Dynasty. But the dust removal electrolysis reaction itself is a chemical change. Conductive electricity is not.

Conduction is a physical change, and the essence of a chemical change is the creation of new substances.

The conductivity of an electrolyte solution is a chemical change!! And it involves redox reactions. How to explain the physical change of copper sulfate solution electrode with copper elemental element?

The electrolyte solution conducts electricity by relying on free-moving ions. Conducts electricity during the directional movement of anions and cations in the electrolyte solution.

Metallic conductors conduct electricity, and the classical conductivity theory holds that it is due to the presence of a large number of free electrons that can move freely inside the metal conductor, and these free electrons move directionally under the action of the electric field force to form an electric current.

1: The conduction of electrolytes is accompanied by chemical reactions. Because the ion must finally gain electrons at the cathode, and must lose electrons at the anode to form a pathway, otherwise it can only form a potential difference and cannot form a continuous current, and the metal conduction is not accompanied by a chemical reaction.

2: The conduction of the electrolyte is the movement of charged ions in the electrolyte to produce an electric current, while the conductivity of a metal is the movement of electrons to produce an electric current (the essence is the overall shift of the electrons).
