Why does zinc displace copper from copper sulphate solution but copper Cannot displace zinc from zinc sulphate solution?

Why does zinc displace copper from copper sulphate solution but copper Cannot displace zinc from zinc sulphate solution?

(i) Zinc metal can displace copper from copper sulphate solution because zinc is more reactive than copper. (ii) Copper cannot displace zinc from zinc sulphate solution because copper is less reactive than zinc.

Why are copper Cannot displace zinc from its salt solution?

(c) A metal can displace a less reactive metal from its salt in an aqueous solution. But zinc is more reactive than copper. Therefore, copper cannot displace zinc from its salt solution.

Why does iron not displace zinc from zinc sulphate?

Iron cannot displace zinc from the zinc sulphate because zinc is more reactive metal . More reactive metal can displace less reactive metal from its salt solution.

Can copper replace zinc from zinc sulphate solution explain?

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.

Why does CuSO4 solution displace copper?

Iron metal is more reactive than copper. Therefore, it can displace copper from copper sulphate (CuSO4) solution. Cu is less reactive than iron, therefore, cannot replace iron from iron sulphate (FeSO4).

Which of the following metal Cannot displace copper from copper sulphate solution?

Iron(Fe) cannot displace copper from CuSO4 solution.

Which metal Cannot displace copper from its salt solution?

Mercury,silver,gold are the metal that cannot displace copper from its solution.

Which metal is displaced when zinc metal is put in solution of copper sulphate a copper B zinc C sulphate D All of the above?

Zn+ CuSo4 → ZnSo4 + Cu Hence copper is displaced and the above reaction is a Displacement reaction in which a more reactive element displaces a less reactive element form is chemical compound .

Can copper sulphate solution replace copper zinc?

Complete step by step answer: So zinc will undergo oxidation and give up two electrons. Thus, zinc can replace copper from copper sulphate solution. The reverse process won’t be possible because copper is less reactive than zinc and also the standard reduction potential of copper is positive.

When copper react with zinc sulphate it will give copper sulphate and zinc True or false?

c) Copper displaces zinc from zinc sulphate solution. This statement is not true because copper is less reactive than zinc and hence cannot displace zinc from its solution.

Does copper displace zinc?

Investigating displacement A tick shows where there is a visible reaction and a cross shows where there is no visible reaction. Magnesium displaces three metals, zinc displaces two metals, iron displaces one metal and copper does not displace any of the other three metals.

Why does copper react with copper sulphate in zinc?

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.

Why can’t copper replace zinc from zinc sulphate solution?

Give reasons for the following. Copper cannot displace zinc from its salt solution. A higher reactive metal can displace less reactive metal from its aqueous salt solution. Hence, copper being less reactive than zinc, cannot replace it from a zinc sulphate solution.

Why does silver displace sulphate from zinc in a reaction?

Silver is lower in the reactivity series than Zinc and therfore cannot displace the Sulphate from the Zinc. But on the other hand zinc is higher than copper, and when displacing the sulphate from the copper it changes colour due to the reaction.

How long does it take for zinc to react with copper?

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 is the difference between zinc and copper in electrochemistry?

Zinc is a more active metal compare to copper. The Zn 2+(aq) ions do not serve as a reducing agent. This is a great demo to present at the beginning of a unit on electrochemistry because it can be followed later in the unit by the zinc/copper cell demo.
