Hydrolysis of cadmium cation in different ionic strength

Document Type : Research Paper




The hydrolysis of cadmium nitrate was studied spectrophotometrically at different ionic strengths
of sodium perchlorate in a wide pH range, 1-12, and at 25 C. Least squares calculations are
consistent with the formation of M(OH)+, M(OH)2, M(OH)3- and M(OH)42- species, which M is
Cd2+. The dependency on ionic strength in the background electrolyte solutions was taken into
account by using a Debye-Huckel type equation, and finally the results have been compared with
data previously reported and interpreted.
