| Sumario: | The first acidic ionization constant of Ni(II) ion as nickelous perchlorate has been determined be a potentiometric titration at constant ionic strength in sodium perchlorate solutions at temperatures ranging from 25 to 50°C. Ni(II) ion concentrations from 2 to 20 × 10<sup>−3</sup> M have been employed. The assembled information indicates the first hydrolysis reaction of this ion is a mononuclear reaction where the complex NiOH+ is formed with ΔG29<sup>8′0</sup> = 13·25 ± 0·1 kcal/mole and ΔH29<sup>8′0</sup> = 7·76 ± 1·0 kcal/mole. |
