Essay on what happens when copper sulphate meets iron

The ratio of the amount of copper produced to the amount of iron used is 1:1

Also, how can it be proved that the copper sulfate solution is in excess after the reaction? / \

The iron is all reacted, and the copper sulfate is excessive.

3:2, for every two trivalent irons, three divalent copper ions can be reduced.

Continue to add ferric iron, if there is precipitation, the copper sulfate is excessive.

fe + cuso4 == cu + feso4

As can be seen from the equation, the ratio is 1:1

The copper sulfate solution is blue, FeSo4 is colorless or light green, as long as the solution is still blue after the reaction, FeSo4 is light green, it indicates that the copper sulfate is excessive.

I remember that it seems to be the formation of ferrous sulfate, which is also positive 2, that is, the ratio is 1:1

Ferrous sulfate seems to be a white solution, copper sulfate is a blue solution, just look at the color. Or continue to put in iron, if it also reacts, the copper sulfate is excessive.

The reaction equation CuSO4 Fe FeSO4 Cu. So the scale factor is 1:1

Number? Does it refer to the iron atoms of the reaction and the copper atoms generated?

Fe+ Cu2+ === Fe2+ +Cu so the ratio is 1:1

If the excess is proven, it can be verified that there is an excess of copper sulfate or that the iron has been reactive.

Therefore, sodium hydroxide can be added to see if there is a blue flocculent precipitate, or to see if the precipitate is magnetic.

According to the chemical reaction equation Fe+CuSO4=Cu+FeSO4, the ratio of the number of units is 1:1

The methods to prove the overdose of copper sulfate solution are:

1) Add a small amount of Fe to observe whether it reacts.

2) Instillation of NaOH shows a blue flocculent precipitate Cu(OH)2

1 to 1, look at the color of the solution, the color of different ions is different.

It should be 1:1

Proof method: Instillation of NaOH showed a blue flocculent precipitate.

A 1:1 drop of NaOH showed a blue flocculent precipitate.

Fe + CuSO4 = FeSo4 + Cu, because Fe is more metallic than Cu, so Cu can be replaced from the copper sulfate solution.

Hello! The chemical equation for the reaction of iron with copper sulfate solution is.

fe +cuso4 =feso4 +cu

Note: Changing the numbers to a small font size is the answer.

A red metal appears on the iron block, and the blue copper sulphate solution becomes lighter blue and gradually turns into a green solution. The type of reaction is displacement reaction.

The solution changes from blue to pale green (provided that the copper sulphate is completely reactive), and the iron nails gradually adhere to the reddish-brown substance. The type of reaction is displacement reaction.

The blue test solution turned light green, and there was purple-red solid precipitation.

Reaction Type: Displacement.

oxidation reaction) (high school).

The red substance disappears, and the blue substance precipitates the displacement reaction.

1. The activity of iron is stronger than that of copper, and iron reacts with copper sulfate to form ferrous sulfate and copper.

2. Reaction equation: Fe+CuSoFeSo+Cu

Reaction phenomenon: iron dissolves, a red substance is formed, and the solution changes from blue to light green.

Reaction principle: Iron ions are more active than copper ions, and copper ions are replaced, or the reduction of iron, reduces copper ions.

Reaction Type: Displacement Reaction. The displacement reaction is that the active substance will be replaced by the lazier substance.

In secondary schools and general chemistry education, copper sulphate is used as an electrolyte for galvanic cells, usually as an anode solution. For example, in a copper-zinc galvanic battery, copper ions in a copper sulfate solution absorb electrons from the zinc to form metallic copper.

The reaction of the ironstone element is not a compound. Besides, it didn't transfer electrons to ions at first.

Iron is elemental iron before the reaction and is in the form of a compound after the reaction. Copper is the same.

Fe in the reactant is solid and not in solution, whereas Fe2+ is only present in solution.

Can you understand the displacement reaction experiment of iron and copper sulfate.

Displacement reaction.

Iron and copper sulphate can react to form ferrous sulphate and copper.

fe+cuso4==cu + feso4

Iron replaces the copper in the copper sulphate.

Displacement reaction.

It is also a redox reaction.

The displacement reaction is also a redox reaction in essence, and I don't understand it.

fe+cuso4=feso4+cu

In junior high school, it's called the displacement reaction.

In high school, it is called a redox reaction, and there is electron transfer taking place.

Downstairs, what about iron ions? Obviously not copper oxide

The correct answer should be iron, excess iron powder and sulfuric acid produce ferrous sulfate, sulfuric acid is consumed, the alkalinity of the solution increases, and ferrous ions can be hydrolyzed into precipitate, so that it is good to filter it out. Ah, give it to me, help you out

Not copper oxide. There's something wrong with your question! Ferrous sulfate should be extracted instead, so that iron powder "black" is added (but the iron element is white, pay attention to the difference).

Not copper oxide.

I didn't see iron sulphate...

I'm not MT

What about the trivalent iron?

Ferric sulfate and ferrous sulphate are not dihydrolyzed.

When the sulfuric acid is consumed, the alkalinity of the solution increases.

No matter how much sulfuric acid is gone, no matter how much other solutions are gone, there will be no alkaline.

Besides, whether it is iron sulfate or ferrous sulfate or copper sulfate, the aqueous solution is acidic.

Ferrous ions can be hydrolyzed into precipitates.

The amount of ferrous ions that can be hydrolyzed is only 1%. How to get rid of it.

The consequence of adding too much iron powder is that all the components in the solution become ferrous sulfate.

Actually, I also think there are some problems with this question.

I remember it was iron oxide.

Because of the strength of ionic oxidation, these are arranged like this: trivalent iron, divalent copper, and divalent iron.

So you can use it to make it.

Probably not, I guess it's probably basic copper carbonate Cu2(OH)2CO3

fe+cuso4==feso4+cu

Iron is more active than copper, and iron and copper sulphate are together and copper is replaced. The displaced copper covers the surface of the iron, and the remaining iron does not come into contact with the copper sulfate, so it does not react. Iron is weakly reducible here, producing ferrous ions.

fe+cuso4=cu+feso4

If you can't replace it, it may be that the reaction is not too obvious, or the content of copper sulfate is too small, and there are more impurities in copper sulfate!

Iron is not chemically reactive, but the reaction is not too slow.

The copper produced by the displacement of iron will cover the iron sheet or wire, which will prevent or delay the continuation of the reaction between the two, so it cannot be 、、、 quickly

Because iron is not chemically active.

Iron powder is not the same as iron blocks.
