Question

A teaspoonful of zinc granules is added to copper sulphate solution and dissolved. What changes do you observe? Write the chemical equation.

Answer 1

zinc displaces copper from copper sulphate solution

Answer 2

when zinc granules is added to the copper sulphate solution a new compound is formed which is called zinc sulphate and copper remains settle at the bottom of the solution and thus displacement reaction occur because zinc is more reactive than copper and thus displaced copper in reaction
Zn + CuSO4 —— ZnSO4+Cu
the solution remains colurless ZnSO4 remains coluress and the brown coloured metal copper settle down at the bottom and also the blue color of the copper sulphate disappear in the solution
