![If a student doesn't add enough HCI to dissolve all of the excess zinc, what effect will
this have, if any, on the %Cu that is calculated for the copper(II) sulfate
pentahydrate?
the calculated %Cu will be higher than actual
the calculated %Cu will be lower than actual
more information is needed to answer this question
no error is created since zinc is not copper and doesn't add to the copper mass
If a student's filter paper tears and some of their copper remains in the filtrate
solution, what effect will this have, if any, on the %Cu that is calculated for the
copper(II) sulfate pentahydrate?
the calculated %Cu will be lower than actual
no error since the amount lost will be negligible
more information is needed to answer this question
the calculated %Cu will be higher than actual
If a a student's filter paper and copper solid retain some moisture even after one
week of drying, what effect will this have, if any, on the %Cu that is calculated for
the copper(Il) sulfate pentahydrate?
the calculated %Cu will be lower than actual
no error because water is too light of a molecule to add mass to a heavy metal
like copper
the calculated %Cu will be higher than actual
more information is needed to answer this question
no error since water is not copper and the water mass isn't included in the
copper mass
Place the following physical and chemical processes for the Percentage of Copper in
Copper(II) Sulfate determination into correct order as they occur during the
experiment (TIP: translate each reaction into words so that you understand what is
happening better)
HCI(aq) + Zn(s) --> Zn2+ + H2(g)
Cu2*(aq) + Zn(s)
--> Cu(s) + Zn2+(aq)
CusO4(s)
Cu2*(aq) + SO42 (aq)
