What does HCL and CuSO4 produce by reaction? Is it H3 CuCl4? What color is it?? 10

It doesn't react, the substance you said doesn't exist, it's still blue.

If you don't react, HCL needs to be thick to react.

Is HCL thin or thick?

This reaction is hydrolyzed and is reversible.

cucl2+2h2ocu(oh)2+2hcl

Because the hydrolysis reaction is in very small amounts, the resulting Cu(Oh)2 and HCl are also very small.

Copper sulphate solution can react with ammonium chloride solution.

Copper ions can be compared with ammonium ions.

A complexation reaction occurs.

Curamide ions are obtained.

Ion equation: Cu2+ +4NH4+ Cu(NH3)4]2+ +4H+

Chemical equation.

CuSO4 +4NH4Cl [Cu(NH3)4]SO4 +4HCl.

This is a question of junior high school or high school, and from the perspective of high school, it is theoretically not reflected.

Hello, there can be no reaction between the two.

Step-by-step reaction to Xinzhina.

2cu+o2=2cuo cuo+ch3ch2oh=ch3cho+cu+h2o

The total anti-slip did not take the Changying formula.

2ch3ch2oh + O2 = 2ch3CHo+ 2H2O Cu as catalyst.

A small amount of ammonia gas is introduced into the copper sulfate solution to produce blue precipitated copper hydroxide, and ammonia gas is continued to be introduced to become a dark blue solution liquid, that is, a copper tetraammonia complex is generated.

Anti-suffocation should be accompanied by a noisy trip:

cu2+ +

cu（oh）2+ +2oh- +4h2o

Hello! This is the elimination of halogenated hydrocarbons.

Therefore, the trembling hand formula of the call-acacia reaction is ch3ch2chclch3+naoh c2h5oh---ch3ch2ch=ch2

HCL is summarized above. The reaction product is CH3CH2CH=CH2 or.

ch3ch=chch3

Anhydrous copper chloride is brownish-yellow, often in the form of (CuCl2)N, and when dissolved in a small amount of water, it forms [Cu(H2O)4]2+ and [CuCl4]2-complex ions

cucl2)2+4h2o==[cu(h2o)4]2++[cucl4]2-

Cu(H2O)4]2+ is blue, [CuCl4]2- is green, and the mixed color when they coexist is green, so the concentrated CuCl2 solution is green.

When diluted, ionization equilibrium due to increased water.

Moving to the right, the [CuCl4]2- ions decrease, the [Cu(H2O)4]2+ ions increase, and the green color changes to blue. When the solution is quite diluted, almost all of them are [Cu(H2O)4]2+, and [CuCl4]2- is very little, so it is blue.

When copper chloride is dissolved in water, a large amount of copper ions and chloride ions are ionized in the aqueous solution.

In general, the copper ion Cu2+ actually exists in the form of the hydrated ion [Cu(H2O)4]2+ in aqueous solution, and the hydrated copper ion is blue, so most of our common copper salt solutions are blue. In the solution of copper chloride, there are not only hydrated copper ions [Cu(H2O)4]2+, but also chloride ions Cl- combined with copper ions to form tetrachlorocopper complex ions [CuCl4]2-, which is yellow in color.

According to the principle of optics, we know that the mixed color of blue and yellow is green, which is why our common general concentration of copper chloride solution is green. If we add water to the copper chloride solution, the concentration of chloride ions in the solution becomes smaller, and the hydrated copper ions increase relatively, and the solution mainly shows the color of hydrated copper ions (blue). So the copper chloride dilute solution we see is generally blue.

2cuso₄+

4nahco₃==cu₂(oh)₂co₃

2na₂so₄

3co₂↑h₂o

Of course, a small amount is also accompanied by side effects: Cuso +2NaHCO ==Na SO +2CO +Cu(OH).

and CuSO4+2NAHCO ==CUCO+NAso+CO+HO

The above reactions have been experimentally tested, and the structure and chemical properties of the basic copper carbonate generated are stable.

Even if a low concentration of CuSO4 solution is added to the bulk CACO, a large amount of basic copper carbonate will be formed after 3 days, and a large number of bubbles (CO) will be attached to the reactor wall. If barium carbonate is added, it reacts quickly, and the phenomenon is extremely obvious.
