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

Using our ending solution from the last reaction, we carefully weighed out about 2 grams of mossy zinc to add! The result of adding the zinc caused fizzing, color change of the zinc (black-red) and resulted in copper formation!

Shown in this video, the stirring of the reaction showed accuracy because the stirring further exposed areas of zinc that needed to react to complete the reaction


Once all the zinc reacted we were left with bits of copper at the bottom of our beaker. We weighed a piece of filter paper, then we filtered our copper to drain all of the water


Single Replacement Reaction! SO4 attaches to Zn instead of Cu! The driving force is transfer of electrons. CuSO4 dissolves the Zn, leaving just Cu!

    Life is like a battle, if you don't know how to defend yourself then you'll end up being a loser. So, better take any challenges as your stepping stone to become a better person. Have fun, explore and make a lot of memories.
