One liter of solution is made containing 10^{- 4} moles of Mn²⁺ and 10^{- 5} moles of Fe²⁺. The [OH^-] is adjusted to 1.82×10^{- 4} M . Which of the following statements is true, given K _sp [Mn(OH)₂] = 4.5×10^{- 14} and K _sp [Fe(OH)₂] = 2.0×10^{- 15}?

Question

Quizplus · Accepted Answer

Given the concentrations of Mn^2+ and Fe^2+ ions and the concentration of OH^- ions, both Mn(OH)_2 and Fe(OH)_2 have solubility product constants (Ksp) that are exceeded under these conditions, leading to the precipitation of both metal hydroxides.
