Calculating Ferric and Ferrous Concentrations - please see the attachment. Thanks.
Solubility product constants describe equilibrium expressions for very weakly soluble salts.
Fe(OH)3 and Fe(OH)2 are both highly insoluble salts.
Fe(OH)3 <-------> Fe+3 + 3 OH-
log K = -38.55
What is K?
Take the antilog of -38.55. K (or Ksp) = ...
The solution uses a step-by-step equational process with explanation throughout to answer the question.
