The solubility diagrams of the system Na[La‐EDTA]–Na[Pr‐EDTA]–H 2 O (EDTA = ethylendiamine‐tetraacetate) have been established at 0°, 35° and 50°. A miscibility gap occurs a t 0° between the solid phases Na[( La , Pr)‐EDTA] 6 H 2 O and Na[( Pr , La)‐EDTA], 8H 2 O, and also at 50° between the latter and Na[( La , Pr)‐EDTA], 3H 2 O. At 35° however, a continuous series of mixed crystals Na[(La, Pr)‐EDTA], 8H 2 O appears as the solid phase in this system.
