Question

Question 1 0/1 pts Suppose some Fe3+ was also formed during the single displacement reaction you performed in the lab to produce copper metal. The percentage (%) yield of the metallic copper product should be: Note: Remember you added an excess of CuSO4 solution in the process Higher than the expected Not affected Lower than the expected Question 2 0/1 pts If the iron powder you employed in the experiment during the lab was originalhy contaminated with small quantity of a Fe2+ salt (FeSO4), the percent (%) yield of copper metal produced should be: Notes: Remember you added an excess of CuSO4 solution in the process. Consider no further oxidation of the Fe2 salt. Lower than the expected Higher than the expected The same as the expected

Explanation / Answer

Question1

Answer

Not affected

Explanation

CuSO4 + Fe - - - - > Cu + FeSO4

3CuSO4 + 2Fe - - - - - > 3Cu + Fe2(SO4)3

Both reactions give metallic Copper, so percentage yield will not affect.

Question2

Answer

Lower than the expected

Explanation

FeSO4 + CuSO4 - - - - - > No reaction

So, percentage yield of metallic copper will be lower than expected.
