What happens when zinc reacts with copper II sulfate?

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 the reducing agent in the reaction of zinc and copper II sulfate?

The two electrons that are released by zinc will be gained by the Cu2+ ions (reduction). The Cu2+ ions become Cu atoms. Since the copper(II) ion has substantially greater reduction potential (+0.15 V) than zinc ion (-0.76 V), it is readily reduced by zinc metal.

What happens when a piece of zinc is added to an aqueous solution of CuSO4 show with the help of electronic theory that this is an oxidation reduction reaction?

As Zinc is more reactive than copper, zinc displaces copper from copper sulphate & forms zinc sulphate solution. This is indicated by colour change from blue to colourless. CuSO4 solution has a blue colour while ZnSO4 solution is colourless. Zn(s) + CuSO4(aq) -> Cu(s) + ZnSO4 (aq).

Why does zinc 2 react with copper II sulfate?

On adding zinc to copper sulphate solution, zinc displaces copper from copper sulphate and forms zinc sulphate solution. It will undergo a redox reaction, called the displacement reaction of metal because zinc is more reactive than copper according to the reactivity series.

What happens when a piece of copper metal is added to a solution of zinc sulphate write the balanced chemical equation?

Also, write the balanced chemical equation, if reaction occurs. Answer. (a) When zinc metal is added to copper sulphate solution, the colour of CuSO4 solution disappears and colourless zinc sulphate solution is formed. Solid brown copper is deposited as it displaces by Zn.

How does zinc react with copper?

That is why copper(II) ions can act as an oxidizing agent when put into contact with zinc metal. However, no reaction will occur if a strip of copper metal is placed into a solution of zinc ions, because the zinc ions are not able to oxidize the copper. In other words, such a reaction is nonspontaneous.

Does zinc react with copper?

Notice that zinc is listed above copper on the activity series, which means that zinc is more easily oxidized than copper. However, no reaction will occur if a strip of copper metal is placed into a solution of zinc ions, because the zinc ions are not able to oxidize the copper.

When a strip of zinc metal is placed in copper sulphate solution then zinc sulphate solution and copper are obtained?

ANSWER : Zinc displaces copper from copper sulphate compound so that copper is set free. The blue colour of copper sulphate solution fades due to the formation of zinc sulphate which is colourless. This displacement reaction takes place because zinc is more reactive than copper.

What happens when zinc metal is immersed in copper(II) sulfate solution?

When zinc metal is immersed in a solution of 0.1 M aqueous copper(II) sulfate solution copper metal plates out on the zinc. The solution is initially blue in color.

What is the reduction potential of copper II sulfate?

Since the copper(II) ion has substantially greater reduction potential (+0.15 V) than zinc ion (-0.76 V), it is readily reduced by zinc metal. The blue color of the aqueous copper(II) sulfate solution is due to the presence of the hexaaquacopper(II) ion in water.

What is the reaction between zinc and copper ion redox?

Single Displacement Reaction: Zinc and Copper (II) Ion REDOX. The solution is initially blue in color. A dark coating of copper metal appears on the zinc within two minutes and when 45 minutes have elapsed, there is a thick coat of copper metal powder on the zinc strip and the blue color of the solution has lightened considerably.

What happens when zinc is added to cucuso4 solution?

CuSO4 solution is blue and when we add zinc to it, the colour start fading due to zinc sulphate formation. As Zinc is highly reactive metal so it posses tendency to displace copper from its compound. That’s why blue color slowly disappear. Which is the best shampoo to use for hair loss? , Avid-reader, tech guy, cyclist.
