Copper and graphite are both conductive, so they are electrolytes

Copper and graphite are both conductors of electrons, and both of them conduct electricity by electrons.

The electrolyte must be an ionic conductor, an electronically insulating material. For example, the conductivity of various aqueous solutions of arithmetic, alkali and salt is achieved by the ions that can move freely in the solution.

In addition, many molten ionic compounds are also electrolytes, such as molten sodium chloride, which also has freely moving ions.

It is almost enough to know the above in the high school context.

Electrolytes are often used in electrochemistry, especially in batteries, such as lithium-ion batteries and fuel cells. The explanation in the encyclopedia is a bit one-sided.

In fact, electrolytes are not limited to aqueous solution systems, for example, the liquid electrolyte used in lithium-ion batteries is composed of lithium hexafluorophosphate or lithium perchlorate dissolved in organic solvents such as polycarbonate.

In addition, solids can also be used as electrolyte materials, and some of the solid-state electrolytes for lithium-ion batteries are currently being studied, through which lithium ions can pass by themselves.

There are four types of fuel cells, and each of them is inseparable from electrolyte materials.

The electrolyte of a proton exchange membrane fuel cell is a thin film of hydrogen-ionic polymers that can be permeable.

The electrolyte of a solid oxide fuel cell is a ceramic material that can pass through cations at high temperatures.

If you say too much, I'm afraid you won't understand.

The simplest understanding of an electrolyte is that the electrolyte must be an ionic conductor (with freely moving ions in it) and an electronically insulating material. or materials that can be dissolved in water, heated and melted, etc.

So graphite and copper are not electrolytes.

Wrong ......First of all, the electrolyte must be compounded ......

...It doesn't seem like you're defined as an electrolyte.

The conductivity of graphite electrodes is better than that of virtual electrodes, which can be proved by graphite for dry batteries.

Graphite is one of the softest minerals, opaque and greasy to the touch, ranging in color from iron black to steel gray, and in the form of crystalline, flaked, scaly, striated large-scale, layered or scattered in pure combustion metamorphic rock. Chemically inactive and corrosion-resistant.

Copper is a chemical element with a chemical symbol of Cu and an atomic number of 29 and is a transition metal. Copper is the only metal that can be produced naturally in large quantities and is also found in various ores (e.g., chalcopyrite, chalcopyrite, bornite, cuprite and malachite) and can be used in industry, engineering and processes in the form of brass, bronze and other alloys in its elemental metal state and in the form of brass, bronze and other alloys.

Summary. Dear dear, it's a pleasure to answer your <>

Although graphite and copper are both good conductors of electricity, copper is more suitable for use in electrical wires. This is because wires must not only conduct electricity, but also have low resistance and sufficient mechanical strength. Compared to copper, graphite has a higher electrical resistance and is brittle and hard, breaking easily.

In addition, the conductivity of graphite is also affected by its structure and shape, so it is difficult to accurately control its conductivity, and it is not suitable for use as wires. Therefore, while both graphite and copper are good conductors of electricity, copper is more suitable for making wires.

A student finds a vial of magnesium chloride mgci2 and assumes that the solid is a good conductor of electricity because it contains magnesium metal, and all metals are good conductors. Do you agree or disagree with the assumption that students are bored? Testimony indicates your point of view.

Cathode: 2cu2+ +4e ===2cu

Anode: 2H2O -4E====O2 + 4H+

Leaving the solution system is Cu and O2, and the ratio of the amount of copper atoms to oxygen atoms is 1:1, so supplementing CuO is also to supplement Cu atoms and oxygen atoms back to the solution at 1:1.

Metals are generally single or alloyed.

Electrolytes are compounds that are dissolved in aqueous solution or, preferably, in the molten state, capable of conducting electricity. According to the strength of its conductivity in aqueous solution or molten state, it can be divided into strong electrolyte and weak electrolyte.

Electrolytes are all substances that are covalently bonded by ionic bonds or polar empty socks. Compounds can dissociate into free-moving ions when dissolved in water or when heated. Ionic compounds can conduct electricity in aqueous solution or in the molten state; Some covalent compounds can also conduct electricity in aqueous solutions, but there are also solid electrolytes that are conductive** displaced by the migration of ions in the crystal lattice.

The number of electrons transferred is 1mol

Because the reaction formula of the precipitated copper is Cu2++2E-=Cu, the relationship between the resulting Cu and the electrons is 1:2

So precipitate copper.

Both 32g according to n = na*n (n is the number of electrons, na is the number of comma 1mol particles, and n is the number of moles).

The number of electrons transferred is, which is 1mol

Because the reaction formula of the precipitated copper is Cu2++2E-=Cu, the relationship between the resulting Cu and the electrons is 1:2

So the precipitated copper is both 32g

According to n=na*n (n is the number of electrons, na is the number of 1mol particles, and n is the number of moles).

Dotting the CuCl2 solution, that is, Cu2+ ions and Cl- discharges, the transfer of electrons is 1mol, and a Cu2+ discharge into Cu requires 2 electrons, so 1mol electrons correspond, so the mass of Cu precipitated by the cathode is.
