What does the soda ash solution react with the copper sulfate solution to produce? What are the phys

Copper carbonate precipitates are generated.

cu2+ +co32- =cuco3↓

Copper carbonate is a blue-green copper salt. It is insoluble in water and does not react with water. At present, no pure copper carbonate has been produced, and only mixtures such as CuCO3·2H2O and Cu(NH3)2CO3 have been synthesized.

The soda ash solution reacts with the copper sulfate solution to form basic copper carbonate.

Equation: 2Na2CO3 + 2CuSO4 + H2O==Cu2(OH)2CO3 +2Na2SO4+CO2

Basic copper carbonate is also called patina, and can be heated to produce CuO, H2O, and CO2. Chemical equation: Cu2(OH)2CO3= =2CuO+CO2+H2O

The product should be basic copper carbonate. However, if you are a junior high school student, you can also consider it copper carbonate if you have learned only what you have learned.

Copper hydroxide Cu(OH)2,, blue flocculent precipitate is generated.

Generate copper hydroxide and sodium sulfate Generate blue precipitate Copper hydroxide is a blue powder, insoluble in water Soluble in acid Sodium sulfate is a white, odorless, bitter crystal or powder, hygroscopic.

The carbonate ions in soda ash are very similar to the copper ions in copper sulfate, which is prone to double hydrolysis reaction to generate copper hydroxide blue precipitate.

The solution becomes colorless and a blue precipitate is formed.

According to the conditions under which the metathesis reaction occurs, it can be known that the blue copper sulfate solution reacts with the sodium hydroxide solution to form sodium sulfate and copper hydroxide precipitate, because the reaction is carried out in the solution;

Therefore, what is generated is a colorless sodium sulfate solution and a blue copper hydroxide precipitate, so the reaction phenomenon is that the solution becomes colorless and a blue precipitate is formed.

First, a blue precipitate of copper hydroxide is generated, and then, when heated, the copper hydroxide is heated and decomposed into water and black copper oxide, so it turns black.

Phenomenon: A blue precipitate is formed, and the solution becomes colorless.

Equation: CuSO4+2NaOH==Cu(OH)2 +Na2SO4

At first, you will see a blue precipitate, but after prolonged exposure to the air, the precipitate will turn black.

The phenomenon of the reaction between the copper sulfate solution and the sodium hydroxide solution: the solution becomes colorless, and a blue precipitate is formed.

The chemical reaction equation is as follows:

cuso₄+2naoh=cu(oh)₂↓na₂so₄

Copper sulfate is dissolved in water to form a copper sulfate solution. Copper sulfate solution (CuSO4) is a sky blue solution, which is weakly acidic, commonly known as bile alum, stone bile, bile alum, and blue alum. Copper sulphate is an important raw material for the preparation of other copper compounds.

Bordeaux liquid can be obtained by mixing with lime milk, which is used as a fungicide. Copper sulphate is also the electrolyte used in electrolytic refining of copper.

Copper sulfate (cupricsulfate), an inorganic compound, chemical formula CuSO4. It is white or off-white powder. The aqueous solution is weakly acidic and appears blue.

However, when Ranzhao crystallizes from the aqueous solution, it produces blue copper sulfate pentahydrate (Cuso4·5H2O, also known as bile alum), which can be used to test the presence of water. After losing the crystalline water ridge after being heated, it decomposes, and is very stable at room temperature and pressure, does not deliquescent, and will gradually weathered in dry air.

Summary. Hello! It's an honor for me to do this

Copper hydroxide solution: because copper hydroxide is an alkaline solid with low water solubility, after adding water and then adding sulfuric acid, the acid and alkali are neutralized, the solid is dissolved, and the heat is released to generate copper sulfate and water. H2SO4+Cu(OH)2=CuSO4+H2O is blue and transparent.

After the reaction of copper hydroxide with dilute sulfuric acid, the blue flocculent precipitate gradually disappears, and the solution is blue, and the chemical equation is: H2SO4 + Cu(OH)2=CuSO4 + 2H2O.

The difference between copper hydroxide and sulfuric acid solution reaction and copper hydroxide solution and sulfuric acid solution reaction.

Hello! It is an honor for me to clarify the topic of Liang Copper hydroxide solution: because copper hydroxide is an alkaline solid, water solubility is small, after adding water and then adding sulfuric acid, the acid is neutralized with the alkali, the solid dissolves, releases heat, and generates copper sulfate and water.

H2SO4+Cu(OH)2=CuSO4+H2O is blue and transparent, copper hydroxide reacts with dilute sulfuric acid, the blue flocculent precipitate gradually disappears, and the solution is blue, and the formula of chemical auspiciousness is: H2SO4+Cu(OH)2=CuSO4+2H2O.

There is not much difference between the two.

When sulfuric acid is added to the solid (or liquid) of copper hydroxide, because the sulfuric acid contains Hashimori bent water, then the copper hydroxide will be stored in a dissolved equilibrium, ionized copper ions and hydroxide ions, and a small amount of ionized hydroxide ions are combined with hydrogen ions to form water, and the concentration of hydroxide ions becomes smaller, so that the dissolution balance of copper hydroxide is positively shifted, and the hydroxide is continuously ionized out, and the hydroxide is continuously combined with hydrogen ions until the copper hydroxide is completely ionized. Therefore, although copper hydroxide is an insoluble base, it can also react with sulfuric acid. Happy Chinese New Year It's cold, please pay attention to keep warm!

The phenomenon of chemical reaction between sodium metal and copper sulfate solution: sodium metal melts into bright balls, swims around on the water surface, makes a "hissing" sound, and colorless and odorless gas is generated, and at the same time, there is a blue oak and reed flocculent precipitation in the reaction vessel.

4. In this chemical reaction, water is also involved in filial piety, and this chemical equation can be separated into two reactions, which are sodium and water reaction to produce sodium hydroxide and hydrogen, and sodium hydroxide and copper sulfate reaction to produce copper hydroxide and sodium sulfate.
