The Gibbs energies of formation of Ti(IV) hydrolysis forms have been obtained, and they can be used to calculate the TiO sub(2) solubility as a function of the hydrogen ion concentration (pH). The dependence of the change of the Gibbs energy during dissolution of various ilmenites on mole fraction o...
