I have some chemistry questions. please get all the answers correct ;)
a) Calculate the standard cell potential for the following cell
Zn (s) | Zn2+ (aq) (1M) || Co2+ (aq) (1M) | Co (s)
answer = __________V
b) The following cell was constructed and found to produce a voltage of 1.08 V.
Co (s) | Co2+ (aq) (1M) || Ag+ (aq) (1M) | Ag (s)
Calculate the standard reduction potential for Ag+ (aq) | Ag (s)
answer = _______V
c) Which of these species is the best oxidising agent?
Co2+(aq) | Zn2+(aq) | Ni2+(aq) | Cu2+(aq) |
Standard Reduction Potentials
Cu2+ | Cu +0.34V
Ni2+ | Ni �0.24V
Co2+ | Co �0.28V
Fe2+ | Fe �0.44V
Zn2+ | Zn �0.76V
Mg2+ | Mg �2.36V
