Abstract

The stability constants of 2, 2‐bis‐hydroxymethyl‐propionates of rare earths have been determined at ionic strength 0,100 (NaClO~4~) at 25.0°C by a potentiometric method. The ligand forms 1 : 1 and 1 : 2 complexes with all the rare earths and weak 1 : 3 complexes with light rare earths only. In these last complexes, it binds in a unidentate way. The dissociation constant of the acid has also been measured.

## Abstract The stability constants of N‐acetylgycinates of some rare earths in aqueous solution have been determined by a potentiometric method, and by a solvent extraction technique. The ligand forms 1:1 complexes which are stabilized by relatively large positive entropies of formation, the corre
