Abstract

Spectra have been measured at passive and transpassive potentials in 0. 5 kmol multiplied by (times) m** minus **3H//2SO//4(pH0. 3), 1 kmol multiplied by (times) m** minus **3 Na//2SO//4(pH 2. 0-12. 0), 0. 1 kmol multiplied by (times) m** minus **3 NaOH(pH 13. 1), and 1 kmol multiplied by (times) m** minus **3 NaOH (pH 13. 7). By comparing the spectra with several reference Ni oxides and oxyhydroxides, constituent substances have been identified. The composition of the films changed with solution pH and electrode-potential.
