The aqueous solution of Cl2, NH3 conducts electricity very well, so are they strong electrolytes?

18. The following statement is correct (

a. CaCO3 has very little solubility in water and its conductivity is very weak, so CaCO3 is a weak electrolyte.

b. CaCO3 has little solubility in water, but all the dissolved CaCO3 is ionized, so CaCO3 is a strong electrolyte.

c. The aqueous solution of chlorine and ammonia has good conductivity, so they are strong electrolytes D, water is difficult to ionize, pure water almost does not conduct electricity, and water is a non-electrolyte.

The answer is b because a strong electrolyte is the part of the solute that dissolves in solution and is able to ionize completely.

In addition, option C, the conductivity of the aqueous solution is good, but the conductive substances at this time are no longer chlorine and ammonia, they have reacted with water, and the other substances generated are strong electrolytes.

Hope mine satisfies you.

Answer baA strong electrolyte is a fraction of a solution that can be completely ionized into ions.

c.Chlorine is elemental, which is neither an electrolyte nor a non-electrolyte, and ammonia reacts with water to form an electrolyte, which itself does not ionize under the action of water.

d.Water is an extremely weak electrolyte.

A. NH4Cl can only be completely ionized in aqueous solution, so it is a strong electrolyte, so A is correct;

B, NH3H2O is a weak base, which can only be partially ionized in aqueous solution, so it is a weak electrolytic vertifolia plant, so B is wrong;

C. Cu is elemental, neither electrolyte nor non-electrolyte, so C is wrong;

D. Ethanol cannot conduct electricity in aqueous solution and in the molten state, so it is a non-electrolyte

High School Chemistry Experiment Comparison of conductivity of different electrolyte solutions under the same conditions.

CO2, NH3 are non-electrolytes, while H2CO3, are electrolytes.

The electrolyte must be in an aqueous solution or in a molten state, and conduct electricity by itself. CO2, NH3, etc., which are dissolved in water, can conduct electricity, not themselves, it is they that react with water to form H2CO3, and conduct, so they are not electrolytes, they are non-electrolytes.

No, it is the substances that can conduct electricity, carbonic acid and ammonia monohydrate after they react with water.

CO2, NH3 are non-electrolytes, while H2CO3 is the electrolyte.

The electrolyte must be in an aqueous solution or in a molten state, and it conducts electricity itself, which is the electrolyte. The CO2, NH3 and other substances dissolved in water can conduct electricity, not themselves, it is they that react with water to form H2CO3, and they conduct electricity, so they are not electrolytes, they are non-electrolytes.

NH3H2O is reversibly generated, ammonia itself is a weak electrolyte, and dissolved in water is a mixture, because it is reversible, it can only be weakly ionized in water NH4+, OH-, and ionized ions can be moved and conducted. At this point, both are present in the solution. Anterior.

The definition of electrolytes and non-electrolytes in high school is not tight.

The definition of non-electrolytes should be understood as follows: Compounds that cannot be [ionized] in water-soluble lead and in the molten state.

NH3 is a non-electrolyte, yes. The aqueous solution of NH3 conducts electricity because the generated ammonia monohydrate is an electrolyte, which can be ionized into ions, NH3·H2O==NH4+ +OH-, and there are freely moving ions in the solution, thus conducting electricity.

This process is not the ionization of NH3 itself, so the conduction of ammonia cannot prove that NH3 is an electrolyte, but can only say that Layun NH3·H2O is an electrolyte.

It cannot be said that ammonia is an electrolyte, because ammonia is a mixed locust spike complex, not a compound.

Electrolytes conduct electricity, and it is not necessarily the electrolyte that conducts electricity.

Electrolyte: A compound that conducts electricity in an aqueous solution or in a molten state.

NH3, which cannot be ionized in water, is not an electrolyte. Rather, it ionizes with NH3·H2O formed by the reaction with water, so NH3 is not an electrolyte, NH3·H2O is an electrolyte.

NH3 gas is composed of NH3 molecules, it has no free ions, only NH3 dissolved in water to form NH3 H2O, can ionize NH4+ and OH-, can conduct electricity, and become an electrolyte.

Electrolyte: Compounds that can conduct electricity when dissolved in water or melted state are called electrolytes.

NH3, SO2, SO3 are not electrolytes, they themselves can not ionize ions and conduct electricity, the reason why they can conduct electricity in aqueous solution is because they react with water to form new substances, and the new substances generated can ionize ions in aqueous solutions to conduct electricity.

SO2 CO2 NH3 is not an electrolyte dissolved in water to form H2O+SO2=H2SO3 H2O+CO2=H2CO3 NH3+H2O=NH4OH can ionize ions.

Mistake. SO2, CO2, NH3 are not electrolytes.

However, when they are dissolved in water, they react with water to form electrolytes.

SO2 and CO2 are acidic oxides that can react with water to form acids.

Acids belong to electrolytes and can conduct electricity.

And NH3 is dissolved in water, and the result is NH3 H2O, which is equivalent to NH4OH and can be regarded as a base.

So it can also conduct electricity.

Wrong, they react with water to form sulfurous acid, carbonic acid, and ammonia monohydrate, sulfurous acid, carbonic acid, and ammonia monohydrate are electrolytes, SO2, CO2, NH3 are not electrolytes.

False, the SO2 CO2 solution can be dissolved in water to form acid ionized hydrogen ions and acid ions to conduct electricity.

NH3 is soluble in water, ammonium ions and hydroxide ions are conductive, and neither is ionized by itself, such as NaCl aqueous solution can conduct electricity, and the melting state can also conduct electricity, and the electrolyte is generally a strong acid, a strong alkali salt.

Iron salt solution is resistant to trembling wrong, is it ferrous or iron.

and 2, double hydrolysis, there is cavity for carbon dioxide generation.

2.The biggest change is sodium hydroxide, which is a strong base, while the other four are weak bases, and the first three of them are hydrolyzed and alkaline.

3.From small to large, it is 5<4<1<2<3, the acidity of acetic acid is greater than that of carbonic acid, so the degree of hydrolysis should be 3 than 1, that is to say, the alkalinity of 1 is larger, then the concentration of the same pH, 3 is larger; In the same way, the first step of carbonic acid ionization is greater than the second step, so the alkalinity of 1 is greater than that of 2, and 4 and 5 are ionized out of hydroxide, and their degree of ionization is greater than the degree of hydrolysis of 123.
