A speciation analysis of concentrated ZnCl,/KCl solutions indicates that four species: Zn2+, ZnCl+, ZnCl; and ZnCl:-, are present in varying amounts in the concentration range studied. Proton NMR spectroscopy performed on several solutions also confirms this. A computer analysis was undertaken to mo

The passivation of zinc electrodes in alkaline solution has been studied at various rates of solution flow. At constant cd the passivation time is increased by an increase Passivation-time/cd data can be correlated in the form in solution velocity. (i -i&l'\* = k, where i, and k arc umstants for giv
## 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
The passivation characteristics of a planar zinc electrode have been examined in 2 M KOH electrolytes containing a variety of additions. The time to passivation has been measured and compared to that of a planar cadmium electrode in 5.3 M KOH. The most promising additives were found to be borate and
It has long been recognized that the oscillation of a fluid in a conduit can lead to an increase in the rate of axial mass transport. Recently it was proposed using fluid oscillations to increase the mass transport and selectivity of supported liquid membranes. The quadratic dependence of the enhan
