Dissolution kinetics of nickel(II) and nickel(III) oxides in acid media

The rate of nickel(II) and nickel(III) oxide dissolution in sulfuric, hydrochloric, and nitric acids was measured as a function of the acid concentration and temperature, and a kinetic model of this process is suggested. The limiting step of the dissolution process is the passage of the complexes forming on the oxide surface into the solution.
