Homework Help: chemistry

Posted by fenerbahce on Sunday, July 22, 2012 at 6:50pm.

the measured cell voltages are supposed to be smaller than the theoretical cell voltages, but when I'm calculating the theoretical cell voltages they are smaller. And I don't know why I'm getting these. Can you please check if I'm doing it right. Thank you.


Measured Cell voltages
1) Zn|Zn^+2 (1M)| Cu|Cu^+2 (1M): 0.947
2) Cu|Cu^+2 (1M)| Zn|Zn^+2 (1M):-0.947
3) Fe|Fe^+2 (1M)| Cu|Cu^+2 (1M):0.703
4) Zn|Zn^+2 (1M)| Cu|Cu^+2 (0.1M):0.906
5) Cu|Cu^+2 (1M)| Cu|Cu^+2 (0.1 M):-0.0143

Theoretical Cell Voltage( my calculataions)

1) 0.42
2) -0.42
3)-0.11
4)-0.450
5)0.31

#5 you did it but the rest I'm not sure.
