 a solution is prepared in which a trace or small amount of Fe2+ is added to a much larger amount of solution.. ...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....which the [OH-] is 1.0 x 10^-2 M. Some Fe(OH)2 precipitates.
