Kinetics of reaction of nickel(II) hydroxide with sulfuric acid

Changes in the concentrations of nickel(II) sulfate and sulfuric acid in the course of the dissolution of nickel(II) hydroxide powder in sulfuric acid of various concentrations at 25, 50, and 75degreesC were evaluated from variation of the electrolyte resistance. The rate constant and activation energies of the dissolution were calculated.
