Reaction on Barium Chloride and Copper(II) Sulfate

 Obtain two beakers which hold 100mL of liquid each
 Put 35mL Barium Chloride in one beaker, and 35mL of Copper (II) Sulfate in the other (for measurement purposes).
Pour the two together in one beaker, and record any changes you see, hear, or feel on the outside of the beaker.
Clean up materials, making sure to properly dispose of chemicals used.
CuSO4 +BaCl2---> BaSO4 + CuCl
Formation of a precipitate
Should see a cloudy blue liquid form

Once we put the Barium Chloride and Copper(II) Sulfate together, they began to form together. At first, they looked separated, but within a few seconds it almost looked like the chemicals were pushing into each other. The color was a really light blue at first, but got a tiny bit darker within 5-10 minutes.

We left the precipitate in a plastic cup for about two weeks, and it began to oxidize, and get harder and turn a thicker color of blue.



This is our solution right after we mixed the barium chloride and copper (II) sulfate together.
