Question

When zinc granules are put in copper sulphate solution and left
undisturbed for sometime, we find that the blue colour of the
solution disappears and a powdery red mass is deposited at the
bottom of the beaker. Write the equation involved. What type of
reaction is this? Explain the observations.​

Answer 1

Answer:

When Zinc granules are kept in copper sulfate solution the blue color of the copper sulfate solution turns colorless. This because the zinc is more reactive than the copper metal in reactivity series. This means that zinc metal can easily displace the copper metal from its salt to form aqueous solution of zinc sulfate.

Answer 2

Answer

Explanation:

When zinc granules are kept in copper sulphate solution, the blue colour of copper sulphate disappears and the solution becomes colourless. Zinc is more reactive than copper and hence displaces copper from copper sulphate solution and forms zinc sulphate. ... Hence, copper cannot displace zinc from a compound.
