THEORY OF ELECTROLYSIS AT CONSTANT CURRENT WITH PARTIAL OR TOTAL CONTROL BY DIFFUSION-APPLICATION TO THE STUDY OF COMPLEXION IONS

摘要: Abstract : A mathematical analysis is presented for the potential-time curves observed in electrolysis at a constant current with mass transfer partially or totally controlled by semi-infinite linear diffusion. Three cases are considered: (1) reversible electrochemical process, (2) irreversible and (3) process preceded first-order chemical reaction. The transition time (tau) which characterizes was derived 3 processes. tau given conditions of same processes 1 2. For last function kinetics Conditions discussed under theory applicable to reduction completions. Dissociation must precede reaction some complexes (Cd(CN) minus power 4); others (Cu ethylene-diamine) reduced directly. rate recombination Cd 2 plus CN about 4 x 10 9 (mol/l) 1- sec 1.
