Single Replacement

In the Copper to Copper lab there is one single replacement reaction. It is Zn+CuSO4=ZnSO4+Cu. This is an example of a physical reaction because of the fact that there is heat being added to the solution. This is the only single replacement in the whole lab.

Double Replacement

The double replacements in this lab was the CuO+2HCl=CuCl+H2O and 3CuCl+2Na3PO4=Cu3(PO4)2+6NaCl. These reactions occur when Cu is bonded with another chemical and added to two other chemicals. The driving force of the first double replacement is a physical reaction which changes the physical apperance of the chemical due to the heat that is add to the chemical when it is place on the hot plate. The second equation is a chemical reaction due to the mixture of the CuCl and the H2SO4 forming the chemical reaction.

2N+CuSO4=ZnSO4+Cu

These two pictures show the last and final steps of the lab. This pictures show how we are trying to add zinc to the solution to try to pull out the copper. The picture on the right shows the reaction between the zinc and the copper solution. This picture show our group striving for accuracy by waiting and hoping the the copper that we started with will pull out of the solution.

3H2SO4+Cu3(PO4)2=3CuSO4+2H3PO4

This picture is what we started with on the last day of the lab it was Cupric Phosphate. We are going to change it to Cupric Sulfate. The picture on the left shows us pouring in the H2SO4 to change the soultion to Cupric Sulfate. These pictures show us striving for accuracy by being careful and exact so that the lab can't be compromized. This is the 6th Part to the lab.

3CuCl2+2Na3PO4=Cu3(PO4)2+6NaCl

This picture show us heating the cupric choride to put in to the filtration system to form Cupric Phosphate. This picture also shows jay stiring the cupric chloride all the time so that the cupric chloride will not explode. This show Jay striving for accuray but not letting the lab explode.

CuO+2HCl=CuCl2+H20

This is the 4th part to the lab where we are changing the cupric oxide to Cupric chloride. This picture shows the 8 ml of HCl poured into the cupric oxide therefore changing the color from black to green. We are forming Cupric Chloride. We strive for accuracy by making sure that all of the copper is washed out of the funnel with water. We wanted to make sure that no copper was lost.

Cu(no3)2=Cuo+H2O

This picture is of the Cupric oxide being filtered into a solid Cupric Oxide.

We would striving for accuracy by the amount of black goo that is put into the filter and making sure that the solution.
