concentration of Fe2+ in equilibrium with Fe(OH)3
Not what you're looking for?
At pH 6.00 and pE 2.50, what is the concentration of Fe2+ (mol/L) in equilibrium with Fe(OH)3? Hint: Use the Nernst equation and the Ksp for the solubility of solid iron (III) hydroxide.
Note: I have already used the solution library examples and have come up with these wrong answers: 1.36e-3, 3.5e-3, 2.6645e-4, 2.9e-4, 5.495e-5 I have work this problem from many angles and I still can't get it. A step by step answer would be nice. Thanks
