Beryllium perchlorate (Be/sup 2+/) forms a colorless complex with salicylic acid as well as with sulfosalicylic acid. The nature of these complexes is studied by ultraviolet spectrophotometry. The absorption spectra at different pH's suggest that the complex formation increases with an increase in pH. Composition of these complexes is studied at pH 4.5 by Job's method of continued variation. The molecular ratio of Be/sup 2+/ to the ligand in both the complexes is 1: 1. Stability constants are determined at ionic strengths 0.02, well as for the Be/sup 2+/-sulfosalicylic acid complex. Thermodynamic stability constants are found by extrapolation and are 1.66 x 10/sup 4/ and 2.24 x 10/sup 4/ for salicylic acid and sulfosalicylic acid complexes respectively; the values of - DELTA F's are 5830 and 6010 cals respectively.
