Exchange cd measurements have been made using the double-impulse method of Gerischer and Krause. Values obtained are greater than those previously reported (part I) using the single impulse method. The exchange cd is independent of the zincate ion concentration and rises to a maximum value at c1z 8
## Abstract In 0,01β0.3 N NaOH solutions and under galvanostatic and potentiostatic conditions Zn(OH)~2~ is formed and is later transformed in oxide of higher valence state. In solutions above 0.3 N ZnO is precipitated after hydrolysis of Zn(OH)~2~ an this ZnO forms a passivating surface layer. Thi
