What reaction takes place between iron and copper sulphate
Scratches on the surface of the oxide layer allow chloride ions to react with aluminium, this effects the cohesiveness of the oxide layer. This allows reaction with the copper II sulfate. Remind students what copper looks like, so that they know what they are looking for.
Answers to student questions Aluminium appears less reactive than copper. The aluminium foil appears unable to displace copper from copper II sulfate solution. Now aluminium is more reactive because it displaces copper. This allows a simple exchange reaction with the copper II sulfate. The interconversion of states of matter is also a physical change. Chemical change: In this change, chemical reaction takes place and completely a new substance with different properties is formed.
There are changes in chemical properties and composition of substance. Materials Required Iron nails, Copper sulphate solution, Test tubes, Stand with clamp, Thread, Sand paper, Petri Dish Procedure Step 1: Two nails are cleaned by rubbing with sand paper so that their colour appears greyish. Step 2: Two stands with clamps are taken and test tube is fixed in each stand. Step 4: Sufficient amount of copper sulphate solution is poured in both test tube.
Step 4: One iron nail is tied with a thread and hanged in one test tube and other end of the thread is tied with the stand keeping in mind that the iron nail is completely immersed in the solution. Step 5: Other iron nail is kept in a petridish for comparison after the experiment. Step 6: Test tubes are left undisturbed for 15 minutes. Step 7: After 15 minutes, iron nail immersed in copper sulphate solution is removed and put in petri dish.
Observation 1. There is a brown coating on the iron nail which was dipped in the copper sulphate solution, whereas the iron nail placed in petri dish shows greyish colour of iron.

Theory Physical Change: These changes can be observed and take place without changing the composition of substances. There are no changes in chemical nature of substance. The changes which can be observed are like change in colour, boiling point, melting point, hardness, density, fluidity, rigidity etc. The interconversion of states of matter is also a physical change. Chemical change: In this change, chemical reaction takes place and completely a new substance with different properties is formed.

Step 5: Other iron nail is kept in a petridish for comparison after the experiment. Step 6: Test tubes are left undisturbed for 15 minutes. When a piece of copper is dipped into a ferric sulfate solution, no reaction is observed.
Concept: The reaction between iron metal and copper II is an oxidation-reduction reaction. What happens when iron nails are placed in copper sulphate Class 8? When iron nails are placed in a copper sulfate solution, iron displaces copper to form iron sulfate. Slowly, the blue color of the copper sulfate solution turns into green. What happens when iron nails are placed in copper sulphate solution write equation also Class 8?
Iron being more reactive displaces copper from copper sulphate solution. In this reaction, the blue colour of copper sulphate fades and there is deposition of copper on the iron nail. What is displacement reaction what happens when an iron nail is immersed in copper sulphate solution Write the reaction? Textbook solution When Iron nail is kept submerged in the solution of copper sulphate, iron displaces the copper from the copper sulphate solution.
This happens due the fact that Iron is more reactive than copper. What happens when iron nails are placed in copper sulphate solution write equation also Class 7? Iron displaces copper ions from an aqueous solution of copper sulphate. It is a single displacement reaction of one metal by another metal.
What happens when iron nails are placed in copper sulphate solution write word equation Class 7? Textbook solution If iron nails are placed in copper sulphate solution then iron reacts with copper sulphate to produce iron sulphate and copper.
