Abstract

The interaction of chrome(III) with tartaric acid is studied by the methods of ion exchange and spectral photometry. It is determined that the complex formation takes place in discrete steps to  Cr$^{3+}$ : HC4H4O$^−_6$ equal to 1:1, 1:2 and 1:3 at temperature 20 ± 2 oC. Stepwise and general stability constants for the complexes are defined.
