What is observed when an iron bar is dipped into a solution of copper 2 sulfate?

When an iron nail is dipped in copper sulphate solution, a brown coating of copper is formed on the surface of iron and the colour of copper sulphate solution changes from blue to light green.

What would you expect to happen if copper metal is placed in iron II sulfate solution?

(i) When a piece of copper is placed in iron sulphate solution then no change will be observed. This is because copper is less reactive than iron, therefore, unable to displace it from its solution.

What happens when iron reacts with copper sulphate solution Write the chemical equation involved in the reaction?

(a) Chemical reaction of iron nail with copper sulphate solution in water. Iron displaces copper ions from an aqueous solution of copper sulphate. It is a single displacement reaction of one metal by another metal. Fe (s) + Cu2 + (aq) —→ Fe2+ (aq) + Cu (s).

When zinc is reacted with a solution of copper II sulfate copper and a solution of zinc sulfate is formed?

Answer: When zinc is added to copper sulphate (CuSO4) solution due to more reactivity of zinc, copper is replaced by zinc and forms zinc sulphate. During the process, the colour of the solution changes from blue to colourless.

What is observed when an iron bar is dipped into a solution of silver nitrate?

When an iron rod is dipped in silver nitrate solution, it becomes silverish.

Why does the colour sulphate solution change when an iron nail is dipped in it?

If an iron nail is dipped in the copper sulphate solution then iron displaces copper from the copper sulphate because iron is more reactive than copper. Therefore the colour of the copper sulphate solution changes.

Why is iron more reactive than copper?

Since, according to the atomic structure, iron has four unpaired shells in its three sub shells, while copper only has one electron. As a result, iron can react faster than copper.

Why can iron be used to get copper from copper sulfate?

Scrap iron is used to displace copper because it is a more reactive, cheaper metal, making it a cost-effective way to produce copper. During the electrolysis of copper sulphate, positive copper ions are attracted to the negative electrode where they take in two electrons and form copper atoms.

Which is more reactive iron or copper?

Copper does not have a higher reactivity than iron. Since copper is less reactive than iron, it does not displace iron from its solution. A less reactive metal is displaced from a solution by a more reactive metal.

What is the word equation for the reaction between iron and copper sulphate?

Fe + CuSO₄ = FeSO₄ + Cu (iron displaces copper in the salt solution; the iron dissolves, turning into solution, and metallic copper of a reddish color is released).

When iron or zinc is added to CuSO4 solution copper is precipitated it is due to?

When iron or zinc is added to CuSO_(4) solution, copper is precipitated. It is due to. In this reaction Cu2+ change in Cu0, hence it is called as reduction reaction.

What happens when iron nail is put in zinc sulphate solution?

No reaction will take place as iron (Fe) is less reactive than zinc (zn) . Hence, iron will not displace zinc from its salt solution. No reaction will take place. this is because iron is less reactive then zinc.

How can I tell if an unknown substance contains iron(II) nitrate?

To tell whether an unknown substance contains iron (II) nitrate or iron (III) nitrate, add a few drops of sodium hydroxide solution: Note that it is the metal that determines the colour.

What happens when iron(III) sulphate reacts with ammonium hydroxide solution?

Iron (III) sulphate gives reddish brown precipitates with ammonium hydroxide solution. This precipitates obtained are insoluble in excess. This test is used for the identification of cations . Was this answer helpful?

What happens when NaOH solution is added to iron(II) chloride solution?

Best answer When NaOH solution is added to the given solutions, Iron (II) chloride gives dirty green ppt. while reddish brown ppt. is obtained with Iron (III) chloride. Please log inor registerto add a comment.

How do you identify transition metal ions in an unknown substance?

Investigating transition metal ions To tell whether an unknown substance contains iron (II) nitrate or iron (III) nitrate, add a few drops of sodium hydroxide solution: if you get a green precipitate, the unknown substance is iron (II) nitrate if you get an orange-brown precipitate, the unknown substance is iron (III) nitrate
