Palladium complexation in concentrated nitric acid solutions was studied by UV/Vis absorption spectrophotometry. The ionic strength of the solutions was fixed to = 1, 3, or 5 M by mixing of HNO $_{3}$ and HClO $_{4}$ . The major palladium species were found to be Pd $^{2+}$ , PdNO $_{3}$ $^{+}$ , and Pd(NO $_{3}$ ) $_{2}$ . The formation constant of PdNO $_{3}$ $^{+}$ was determined to be $_{1}$ = 1.32 ( = 1 M), 1.49 ( = 3 M), or 1.47 ( = 5 M), while that of Pd(NO $_{3}$ ) $_{2}$ to be $_{2}$ = 0.45 ( = 3 M) or 0.14 ( = 5 M).
