Question

what is deplacement reaction?what happen when zinc is added to copper sulphate solution?explain your statement.

Answer 1

It is the reaction in which high reactive element displaces less reactive element from its compound.
When zinc is added to copper sulphate solution, then the blue colour of solution disappears.
It happens because zinc is more reactive than copper so it displaces copper from copper sulphate solution and forms zinc sulphate solution.

I hope it will help you.

Answer 2

Answer:

When zinc and copper sulphate react in the aqueous state, a simple displacement reaction will take place in which the zinc will displace the copper from the copper sulphate to form zinc sulphate. The colour of the solution will go from blue to colourless due to the change in the cation of the compound.
