CuSO4(aq)+Zn-->Cu(s)+ZnSO4(aq)

Techniques

• We used plastic tweezers rather than metal tweezers because metal reacts with the zinc.
• Using the plastic tweezers, we carefully selected and weighed 2 mg of zinc.
• We made sure not to inhale the zinc as it fizzed in our solution.
• Finally we managed to pull out the last of the remaining fizzing zinc.
• This reaction was the single replacement reaction and this reaction is occurring because the Zn has a stronger electronegativity so it is stealing the SO4 away from the Copper
