Sometimes solubility can be increased by removing a ion in solution by adding a reactant to combine with one of the ions formed. Consider an aqueous mixture made by adding 0.1 mole of Fe(OH)3 (solid) to 1 Liter of water. Most of the solid did not dissolve because the Ksp of ferric hydroxide is very small at 3 x 10^-39. However, when a certain amount of strong acid was added, the entire amount of solid dissolved. Determine the pH of the solution at that point that the entire iron (III) hydroxide dissolved.
Assume that the volume remains constant when the base is added. my pKa is 4.34, mol HA is 0.302, my concentration ratio is 0.51, but how do I get moles of strong base initially added
