Notes:
   a  The solid phases are: A = Al(CHO2)3•3H2O; B = LiCHO2•H2O.

Method/Apparatus/Procedure:
   The isothermal method was used. Three weeks were allowed for equilibration. The lithium content of both phases was determined by flame photometry. The aluminum content was determined complexometrically. The composition of the solid phases was determined by Schreinemakers' method, by IR spectroscopy, DT analysis and x-ray diffraction.

Source and Purity of Materials:
   Aluminum formate was prepared as described earlier1, and so was lithium formate2.

Estimated Errors:
   Solubility: No information is given.
   Temperature: No information is given.
