However, other compounds like oxide Fe2O3 (hematite) and iron(III) oxide-hydroxide FeO(OH) are extremely insoluble, at least at neutral pH, due to their polymeric structure. Therefore, those soluble iron(III) salts tend to hydrolyze when dissolved in pure water, producing iron(III) hydroxide Fe(OH)3 that immediately converts to polymeric oxide-hydroxide via the process called billy streamerWebthe solubility product is given by Ksp (A a B b) = [A +] a ∙ [B -] b The value of the solubility constant depends only on temperature for a given salt.
