Here's why and what happens:
* Zinc is more reactive than copper. This means zinc has a stronger tendency to lose electrons and form positive ions.
* Copper sulfate solution contains copper ions (Cu²⁺) and sulfate ions (SO₄²⁻).
* When zinc is placed in the copper sulfate solution, the zinc atoms will displace the copper ions from the solution. Zinc atoms will lose electrons to form zinc ions (Zn²⁺), and the copper ions will gain electrons to form copper atoms (Cu).
The chemical equation for this reaction is:
Zn(s) + CuSO₄(aq) → ZnSO₄(aq) + Cu(s)
Here's what you'll observe:
* A reddish-brown solid will form on the surface of the zinc. This is the copper that is being displaced from the solution.
* The blue color of the copper sulfate solution will gradually fade. This is because the copper ions are being removed from the solution.
In summary, zinc and copper sulfate solution will react to form zinc sulfate solution and copper metal. This reaction demonstrates the relative reactivity of metals.
