For example, magnesium is more reactive than copper. When a piece of magnesium is dipped into blue copper sulfate solution: brown copper coats the surface of the magnesium.

carried out, the copper ions discharge at the cathode. However, no copper ions enters in the electrolyte from anode. Thus concentration of copper ions goes on decreasing. This result in fading of blue colour.

Since Copper is less reactive than Zinc, no reaction will take place. Cu + ZnSO4 ————-> No REACTION. However if Zinc is added to a solution of copper sulphate, zinc metal will dissolve and copper will be precipitated or deposited.

Metal Zinc will replace cu from copper sulphate as it is more reactive.

Copper is less reactive than zinc. Therefore, it cannot displace zinc from its salt solution. Sodium and potassium are highly reactive metals.

iron

Answer: d] NiSO4. Copper will only be able to displace Ag from AgNO3 because Cu is more reactive than only Ag and rest other metals are more reactive than Cu….

Iron displaces copper ions from an aqueous solution of copper sulphate. It is a single displacement reaction of one metal by another metal.

Iron(Fe)

CuSO4+Ag⟶ no reaction.

Answer. When silver and gold are placed in a copper sulphate(CuSO4) solution no reaction occurs . This means silver and gold cannot displace copper from the copper sulphate solution . Hence it shows that silver and gold do not react with copper sulphate solution .

In the above reaction silver will not react with copper(II) chloride in solution as silver (Ag) is less reactive than copper (Cu) so silver…

Copper is present below hydrogen in the reactivity series of metals. So it does not react with dilute acids like hydrochloric acid or sulfuric acid.

Oxidized copper is a specific type of corrosion that is produced during a three-step process where copper oxidizes to copper oxide, then to cuprous or cupric sulfide, and finally to copper carbonate. It results in a green-colored copper layer or patina that forms over time.

Copper (II) oxide, is a black solid, which, when reacted with sulphuric acid creates a cyan-blue coloured chemical called copper II sulfate. Copper (II) oxide reacts with sulfuric acid to create water and copper (II) sulfate.
