Section Two: Part One B.

Day Two.

After the CuO sat for a couple of days we had to filter all the liquid out to move on to the next step.

 

Corey, again is STRIVING FOR ACCURACY. Corey is being very careful that he doesn't have the Copper does go down into the liquid, making sure the filter is going at the right pressure.

 

After picture.

After we filtered as much liquid possible out of the CuO, we went to the next step by adding HCl. The HCl turned the Copper a green color, which broke down the Copper and  made it a liquid again. The HCl made the Copper go back down into the beaker so we could move on.

Before picture.

Our group was STRIVING FOR ACCURACY by washing out the filter paper with water to make sure that the whole remaining Copper

is washed out into the beaker, which forms CuCl_2.

Austin is STRIVING FOR ACCURACY by measuring out the correct amount of Na₃PO4 to mix into the CuCl_2. 

When mixing those two solutions together it makes Cu₃(PO₄)_2.

When we got the Cu₃(PO₄)2, we mixed H₂SO_{4 together, which forms} CuSO_{4 as a liquid and the solid is} H₃PO_4.

_{Which is the picture below.}
