ResumoThe heat of precipitation for the reaction of zinc ion with the phytate ion in aqueous solution has been determined. The reaction is endothermic. From the value of the equilibrium constant associated with the reaction, the entropy change has been calculated. The entropy change is large and positive. This is consistent with the view that when zinc reacts with phytate to form solid zinc phytate there is an increase in the number of particles in the system.
