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.
Reactivity series(metals):
Potassium
Sodium
Lithium
Calcium
Magnesium
Aluminium
Zinc
Iron
Tin
Lead
Copper
Silver
Gold
Platinum

Why does the concentration of tin sulphate solution not change during the electrolysis?
The concentration of tin sulphate solution does not change during electrolysis because the tin ions are deposited onto the cathode to form solid tin metal, while the sulfate ions remain in the solution. This maintains a constant concentration of tin ions in solution.
Why does the color of copper sulphate change when an iron nail dipped in it?
When an iron nail is placed in a copper sulphate solution, iron displaces copper from copper sulphate solution forming iron sulphate, which is green in colour.Therefore, the blue colour of copper sulphate solution fades and green colour appears.
The blue colour of the solution fades during the electrolysis of copper sulfate. Explain why.?
Why does the colour of copper sulphate solution change when an iron nail is dipped in it? When an iron nail is placed in a copper sulphate solution, iron displaces copper from copper sulphate solution forming iron sulphate, which is green in colour. Therefore, the blue colour of copper sulphate solution fades and green colour appears.
Why does the color with sulphate change?
When a compound containing sulfate ions reacts with another compound, a new compound may form with a different color due to changes in the electronic structure of the atoms involved in the reaction. This change in color is often the result of absorption or reflection of certain wavelengths of light, leading to a different perceived color.
Why colour of copper sulphate solution changes to light green when iron filings are added?
The color change occurs because the iron filings react with copper sulfate, forming iron sulfate and copper. This reaction results in a displacement reaction, where the iron displaces the copper in the compound. This changes the chemical composition of the solution, resulting in a light green color.
What would you see if you dropped a piece of magnesium ribbon into some copper sulphate solution in a test tube?
If you drop a piece of magnesium ribbon into copper sulphate solution, you would observe a redox reaction where the magnesium displaces the copper in the solution. This results in the formation of copper metal and magnesium sulphate, with a color change from blue to colorless as the reaction progresses. Additionally, there may be bubbling and fizzing observed as the reaction occurs.
What happens when an iron nail is dipped in copper sulphate solution?
A brown layer of copper gets deposited on iron nail. This change is due to a chemical reaction between copper sulphate and iron. Also the colour of the solution changes from blue to green due to the formation of iron sulphate. This reaction can be represented by the following equation: Copper sulphate + Iron = Iron sulphate + Copper solution (CuSO4) + (Fe) = (FeSO) + (Cu)

When zinc rod is dipped in zinc sulphate sol then concentration of solution after time will be?
The concentration of the zinc sulphate solution will not change when a zinc rod is dipped into it. This is because zinc is already present in the solution as zinc ions, so the addition of a zinc rod will not alter the concentration of zinc ions in the solution.
What energy change was observed when a seed is added to a supersaturated solution?
Nucleation is an endothermic process.
Is copper sulphate dissolves in water a physical or chemical change?
A physical change is different from a chemical change in two ways:1) In a physical change no new substances are made; in a chemical change new substances are made.2) A physical change can be easily reversed; a chemical change cannot be easily reversed.Dissolving copper sulphate in water does not produce a new substance. The copper sulphate solution is a mixture, not a pure substance.Also, by evaporating the water you can easily get the copper sulphate back again.So, dissolving copper sulphate is a physical change.Sometimes, though, when water is added to copper sulphate, it reacts with the water to form copper sulphate pentahydrate, which is a new compound. This would be a chemical change, but actually dissolving it is indeed a physical change only.See these sites for more information:http://www.bbc.co.uk/schools/ks3bitesize/science/chemistry/chem_react_2.shtmlhttp://www.chem4kids.com/files/matter_chemphys.html

Why is there no colour change when a silver rod is put in blue copper sulphate solution?
When a silver rod is placed in a blue copper sulphate solution, there is no visible color change because silver is less reactive than copper. This means that silver does not displace copper from copper sulfate solution during the reaction, so the blue color of the copper sulfate solution remains unchanged.
What would happen if you put iron into a blue copper sulphate solution?
There would be copper deposited in the piece of iron and the solution would show a color change from pale blue to pale green.
Copper sulphate add to sodium hydroxide result colour?
When copper sulfate is added to sodium hydroxide, a blue precipitate of copper hydroxide is formed. The color change observed is from the initial blue color of copper sulfate to the blue precipitate of copper hydroxide.
Why does the water colour change to blue when copper sulphate was added?
Anhydrous copper(II) sulphate is white. When added to water, it forms a solution of CuSO4(aq) which is blue because of the Cu2+ ion, which is itself a transition metal ion.
