Wht happens when zinc strip is dipped into copper sulphate solution?
Zinc is higher than copper in the electrochemical series, so will displace copper from it's solutions.
Zn + CuSO4 = Cu + ZnSO4
- 0
Adding zinc strip to copper sulphate solution will result in a displacement reaction that will create copper metal to precipitate as a solid.
Zn + CuSO4 = Cu + ZnSO4
This reaction is quite exothermic too, meaning it will give off a lot of heat - enough to make it too hot to hold the reaction beaker in bare hands.

When a strip of zinc metal is placed in copper sulphate, then zinc sulphate solution and the copper are obtained.
The balanced equation for the reaction takes place is:
CuSO4(aq) + Zn(s) -----> ZnSO4(aq) + Cu(s)
The type of reaction involved is "displacement reaction".
