What happens when zinc metal is added to a solution of CuSO4?

Answer: When zinc is added to copper sulphate (CUSO4) solution due to more reactivity of zinc, cooper is replaced by the zinc and forms zinc sulphate. During the process, the colour of the solution changes from blue to colourless.

What happens when you combine copper sulfate and zinc?

When a strip of zinc metal is placed into a blue solution of copper(II) sulfate ( Figure below ), a reaction immediately begins as the zinc strip begins to darken. If left in the solution for a longer period of time, the zinc will gradually decay due to oxidation to zinc ions.

What happens when zinc is added to sulphate?

Answer: When zinc is introduced to an iron sulphate solution, the colour of the iron sulphate solution changes. Since zinc is more reactive than iron, it displaces iron from its iron sulphate solution, resulting in a grey precipitate of iron and a colourless zinc sulphate solution.

Which metal is displaced when zinc metal is put in the copper sulphate solution?

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 type of reaction is the reaction between copper sulphate solution and zinc plate?

oxidation-reduction reaction
Hint: The reaction between zinc and copper sulphate solution is an oxidation-reduction reaction or we can say redox reaction, in which there is transfer of electrons takes place in between two species. During this reaction zinc sulphate solution is obtained.

When zinc is added to dilute hydrochloric acid hydrogen is given off why?

The Questions and Answers of Assertion : When zinc is added to dilute hydrochloric acid, hydrogen is given off. Reason : Hydrogen chloride molecules contain hydrochloric acid and hydrogen atoms.

What will happen when silver metal is added to copper sulphate solution?

Therefore, when silver Ag metal is added to copper sulphate CuSO4 solution, no reaction takes place as silver is less reactive than that of copper and cannot displace copper from its solution. Hence, when a piece of silver metal is added to copper sulphate solution there will be no reaction.

Why does zinc plate develop holes in copper sulphate solution?

Zinc reacts with the sulphate ion present in zinc sulphate solution and displaces copper. As the zinc is removed, so holes develop.. Because zinc +cuso4 and forms znso4+cu. Hence zinc present in plate goes out forming holes in the plate & copper is deposited separately.

When a zinc rod is suspended in copper sulphate solution?

As zinc is more reactive than copper, zinc will displace copper from its solution and will start forming zinc sulphate solution. Number of changes can be seen when zinc rod is placed directly into the solution containing copper sulphate: The blue color of the solution will eventually fade and disappear after sometime.

When zinc metal is added to dilute hydrochloric acid hydrogen is given off?

The metal zinc readily reacts with hydrochloric acid to produce hydrogen ga s (H 2 ) and zinc chloride (ZnCl 2 ).

Why are gas bubbles observed when the sodium bicarbonate is added to dilute hydrochloric acid?

The bubbles are seen due to formation of gas that is carbon dioxide .

What happens when a piece of 2m I zinc metal is added to CuSO4 solution II silver metal is added to CuSO4 solution?

Reason Zinc reacts with copper sulphate to form colourless zinc sulphate solution and solid copper in deposited form. (iii) No reaction occurs. Reason Silver metal is less reactive than copper, therefore, it cannot displace copper from copper sulphate solution.

What happens when copper is added to zinc sulphate solution?

(A):No reaction takes place as copper is less reactive than zinc. (B):The solution becomes colourless and Zn metal gets deposited. (C):The solution remains blue and Zn metal gets deposited.

How long does it take for copper to appear on zinc?

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 an iron solution?

Answer: When zinc is introduced to an iron sulphate solution, the colour of the iron sulphate solution changes. Since zinc is more reactive than iron, it displaces iron from its iron sulphate solution, resulting in a grey precipitate of iron and a colourless zinc sulphate solution. The chemical equation of the reaction,

What did a student add to copper sulphate solution?
