What is the standard reduction potential of the Y1+/Y
redox couple if the cell potential of the following cell at 25
oC is 0.98 V?
Zn / Zn2+ (0.34 M) // Y1+ (1.1 M) / Y
Eo =
What is the cathode pH in Co/Co2+(1.00
M)//H1+(x M), H2(1.0 atm)/Pt if E = 0.06 V?
Give the pH to 0.01.
pH=
The standard reduction potential for the
F2/2F- redox couple is +2.87 V
This means that:
F2 is a good reducing agent
F2 is a good oxidizing agent
F- is a good reducing agent
F- is a good oxidizing agent
The smaller reduction potential of a redox couple indicates its
stronger tendency to donate electron.

cathode?
7. Given the standard reduction potential for the following two
half-cell reactions (in the presence of 1.00 M HCl):
Fe3+ + e <==> Fe2+, E0 = + 0.68 V
AsO4 - + 2H+ + 2e <==> AsO3 - + H2O, Eo = +0.559 V.
Please calculate the system potential at the equivalence point
when Fe3+ was used to titrate AsO3 - in the presence of 1.00 M
HCl.
Answer: 0.60 V
The cell potential of a redox reaction occurring in an
electrochemical cell under any set of temperature and concentration
conditions can be determined from the standard cell potential of
the cell using the Nernst equation E = E° − RT nF ln Q where E is
the cell potential of the cell, E° is the standard cell potential
of the cell, R is the gas constant, T is the temperature in kelvin,
n is the moles of electrons transferred in...
