Abstract: | The stability constants for the formation of Cu(tet a)X]+(blue) from Cu(tet a)]2+(blue) and X- (where X=Cl, Br, I) were determined by spectrophotometric method at 15°, 25° and 35°C. The corresponding ΔH° and ΔS° values were obtained from the variations of the stability constants between 15° and 35°C. For the same halide ion, the stability constant of Cu(tet b)X]+ (blue) is larger than that of Cu(tet a)X]+(blue). |
