Abstract
Spectrophotometric investigations were performed in the
visible spectral region of Co(II), Ni(II) and Cu(II) solutions in
the presence of sodium salt of formic, acetic, propionic, butyric,
glycolic and chloroacetic acid. On the ground of spectrophotometric
data, applying the method of corresponding solutions after
J. Bjerrum, the stability constants of present complexes were
determined by Fronaeus' graphic method. On the basis of these
values the values of stability constants were then calculated
together with the corresponding error limits by means of a
digital computer by applying the Gauss Z programme after R. S. Tobias.
