...which the [OH-] is 1.0 x 10^-2 M. Some Fe(OH)2 precipitates. The value of Ksp for Fe(OH)2 = 8.0 x10^-10.

A. Assuming that the hydroxide is 1.0 x 10^-2 M, calculate the concentration of Fe2+ ions in the solution.

B. A battery is prepared using the above solution with an iron wire dipping into it as one half-cell. The other half-cell is the standard nickel electrode. Write the balanced net ionic equation for the  cell reaction.

c. use the nerst equation to calculate the potential of the above cell.

Fe2+ + 2e- -> Fe(s)  Volts -0.15
Ni2+ +  2e- ->Ni(s)     Volts 0.00
Fe2+ + 2e- -> Fe(s)  Volts -0.15
Ni2+ +  2e- ->Ni(s)     Volts 0.00
