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.

Cu(NO3)2+2NaOH=Cu(OH02+HaNO3



This is a picture of step two where the blue cupric nitrate solution reacts with aqueous sodium hydroxide to form blue cupric hydroxide and sodium nitrate.


This picture shows Jay pouring the solution in to the blue solution showing his accuracy with measuring and pouring.

Cu+4HNO3=Cu(NO3)2+2H2O+2NO2


This is the very first step to the Copper to Copper Lab...

This is when the Soild Copper is being reacted with Nitric Acid to form a liquid of Cupric Nitrate.This picture shows Chenelle was demonstrating the accuracy of measuring the correct amount of Nitric acid.

This is a Video of the reaction of copper with Nitric Acid.
