What Is The Solubility Product Constant For Fe3(PO4)2?

The solubility product constant (Ksp) for Fe3(PO4)2 at 25°C is 2.07 x 10^-22. This value represents the equilibrium constant for the dissolution of solid Fe3(PO4)2 into its constituent ions in a saturated solution. It can be calculated from the concentrations of Fe3+ and PO43- ions in the solution at equilibrium using the expression:

Ksp = [Fe3+ ]^3[PO43- ]^2

where [Fe3+] and [PO43-] are the molar concentrations of the respective ions in the solution. The Ksp value provides important information about the solubility of Fe3(PO4)2 in solution and can be used to predict the extent of precipitation or dissolution under different conditions.
