| Short description | In this experiment we are going to look at the oxidation-reduction (Redox) reaction between Copper Sulphate (CuSO4) and Iron Metal (Fe). This experiment is very important for 3 fundamental reasons: 1. It is one of the most important reactions in chemistry (oxidation-reduction (Redox) reaction). 2. Through this reaction we are going to achieve the circulation of electrons (the principle of electricity in batteries and cells) and 3. we are going to obtain copper metal from other substances. It is the reaction between copper sulphate in solution and iron metal. |
We first look at the oxidation potentials of the components:
Fe2+(aq) + 2e- → Fe(s) 0.440V
SO42-(aq) + 4H+(aq) + 2e- → 2H2O(l) + SO2(g) -0.17V
Cu2+(aq) + 2e- → Cu(s) - 0.340V
We see that the materials with the greatest potential to enter into oxidation-reduction would be the atom from Iron (which is oxidised) and copper (which is reduced). On the other hand, the reaction will take place in an aqueous solution of copper sulphate, which would be sufficient to conduct the electrons that are going to be transferred. To increase the conductivity of the solution we are going to add sodium chloride (common salt), in this way our reaction will be accelerated and we will be able to see the effects more quickly.
The reaction that will therefore take place is:
CuSO4 + Fe -> FeSO4 + Cu
As soon as the iron metal is introduced into the copper sulphate solution, a reddish layer starts to form on the iron in a few minutes, this is already the reduced copper (copper metal) that is being deposited on the iron. Furthermore, the solution changes from the bluish colour of the copper sulphate to the green colour of the iron sulphate that is being generated. If we maintain the reaction over time, the copper will continue to deposit until all the copper in the solution is consumed (or until all the iron is consumed, which in this case would not be the case because there is more iron than copper sulphate).
COPPER IRON SULPHATE REACTION EXPERIMENT STEP-BY-STEP
- Introduce Copper Sulphate in Water in a container. You can find copper sulphate in Alquera
- Introduce some salt (sodium chloride) into the solution.
- Put the Iron Plate in
- Wait a few minutes and you will see the reaction start to occur.
You can find a similar reaction from the Copper Sulphate with Aluminium
The chemical equation mentioned in the article is wrong.
CuSO4 + Al -> FeSO4 + Cu
is an atrocity.
The correct is
CuSO4 + Fe -> FeSO4 + Cu
Thank you, yes, corrected 🙂
I have a question, with what elements does copper react?
Te nmssss jajajajja
The reaction is due to the ability of the ?
Thank you
The equation is wrong, because instead of putting Fe, they put Al
Thank you, yes, corrected 🙂
I want to know if there is a way to stop the rust on the metal from advancing.
At the end of the short description, there is still the term "aluminium" as part of the reaction
Thank you!
I performed a similar experiment by applying hydrochloric acid (HCl) to a rock containing antlerite (Cu3SO4(OH)4), then I scraped it with a nail and it took on a reddish colour which is supposed to be due to the dissolution of the copper that the atacamite contains and which is then impregnated in the nail. My question is, how would the chemical equation work if I have molecules (apart from copper sulphate and iron) of OH and HCl involved in the equation?
Very good, thank you 👍
What happens if we reverse the process?
What applications in everyday life are there based on this phenomenon?
An analysis of this experiment?
What would happen if we use magnesium instead of iron? Would it be the same?
This is the result of the chemical reaction between copper sulphate and iron.
CuSO4 + Fe -> FeSO4 + Cu
If we continue with the chemical reaction to precipitate the iron contained in our resulting solution, with which reagent can we cause the iron to precipitate?
which substances are involved in this reaction ?
Hello everyone, a question I would like someone to help me to join copper sulphate + sodium carbonate + sodium ferrocyanide, to obtain copper (II) Hexacyanoferrate (II), is to make a well land, please someone who can help me how I can join these three molecules, thanks ....
Do you know which pictograms we have to follow?
which chemical reactions are of the same style
?
