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
