Question

The proper procedure of the exeperiment to sho that zinc is more reactive than copper is ... .

Answer 1

Aim : to show that zinc is more reactive than copper

material required : copper sulphate solution , zinc granules , beaker etc...

principle of experiment : to show that zn is more reactive that copper by a practical approach

procedure : 1. take a 100ml beaker containing the copper sulphate solution

(CuSO4)

2. take some zn granules

3. put them into the beaker containing the cuso4 solution

4. note down the observation

draw a diagram for the above activity

observation : when the zn granules are added to the cuso4 solution the blue color of the solution disappears and the solution become colorless showing the displacement of copper

reaction : CuSO4 + Zn ⇒ ZnSO4 + Cu

conclusion : in the above reaction the zinc displaces copper from the copper sulphate solution as the solution becomes colorless showing the presence of zinc.
