Reaction Types

The Double Replacement reactions are the Reactiond within Parts E and F.

Part E: The formation of a solid with in a solution is the driving force.

Part F: The formation of a liquid is the driving force.

Part G: CuSO4 + Zn --> Cu + ZnSO4

Equation: CuSO4 + Zn --> Cu + ZnSO4

Reaction:






The Zn is replacing the Cu to make solid Cu. This is the only single replacement reaction; this is because of the fact that Zinc (Zn) has a stronger electron charge and need than Copper (Cu).



This is the Zinc replacing Copper.


End Product:


The Copper left over from the reaction.

Part F: Cu3(PO4)2 + 3H2SO4 --> 3CuSO4 + 2H3PO4

Equation: Cu3(PO4)2 + 3H2SO4 --> 3CuSO4 + 2H3PO4

Reaction:


By Adding the H3PO4 to the Cu3(PO4)2 the copper will bond with the SO4.



Accuracy:


We strive for accuracy when measuring the H3PO4.

Part E: 3CuCl2 + 2NA3PO4 --> Cu3(PO4)2 + 6NaCl

Equation: 3CuCl2 + 2NA3PO4 --> Cu3(PO4)2 + 6NaCl


Reaction:


Adding the NaOH one drop at a time to neutralize the solution.



Adding the Na3PO4 causes a precipate to form which settles to the bottom.





Accuracy:



Striving for an accurate amount of NA3PO4.

Part D: CuO + HCl --> CuCl2 + H2O

Equation : CuO + HCl --> CuCl2 + H2O


Reaction:




Introduction of HCl to the CuO. This dissolves the Oxidized Copper and becomes Cupric Phosphate.

Accuracy:

Striving for Accuracy by measuring at eye level.

Part C: Cu(OH)2 + H2O --> CuO + 2 H2O

Equation: Cu(OH)2 + H2O --> CuO + 2 H2O


Reaction:



The mixture from part B and distilled water on the Hot plate.


Copper Oxidizing from Cupric Hydroxide.


Filtering out the Cupric Oxide.

Part B: Cu(NO3)2 + 2NaOH --> Cu(OH)2 + 2 NaNO3

Equation: Cu(NO3)2(l) + 2NaOH(l) --> Cu(OH)2(aq) + 2 NaNO3(aq)

Reaction:
This is the blue slurry formed by Cu(OH)3.

Accuracy:

When measuring 5 ml of NaOH be very careful and accurate.

Part A: Cu(s) + 2HNO3(l) --> Cu(NO3)2(l) + H2(g)

Part A: Cu(s) + 2HNO3(l) --> Cu(NO3)2(l) + H2(g)





Step one measuring the HNO3 (Accurately)

Reaction:



This is the H2 gas leaving the solutions of Copper and Nitric Acid. This forms Copper Nitrate.
