The purpose of work is to establish features of processes formation of a firm and gas phase, at electrolysis. Method of research is studying of electrochemical characteristics and mathematical modelling. The features of oxygen and hydrogen bubbles formation at the moment of their association is considered. The model of association of gas bubbles explains sharp acceleration of growth of bubbles which is observed on initial growth stage is developed. The effective average degree of increase, increases from 1,5 up to 2,5-3, 3. Conductivity thin liquid layers near a surface air - electrolyte has been investigated. Abnormal high conductivity of a superficial layer has been established. Probable mechanism of charge transfer has been proposed. The new mechanism of electrochemical topochemical reactions is offered. Substantial increase of conductivity of active substance is experimentallyconfirmed as a result of introduction of lithium a manganous electrode. Explanations of this process from the point of view topochemical the mechanism of reactions are given. The model of electrochemical processes , reaction in which proceeds under the scheme: dissolution - electrochemical reaction - crystallization is expanded. On the basis of model the conclusion which even very poorly soluble substances at increase in dispersiveness can show electrochemical activity is made. Results of work were included in the textbook on electrochemical power (M.Koshel). The forecast concerning development of object of researches may be connected with optimization of active mass structure and technologies of chemical power sources. Fields of application - electrochemistry. Product Description popup.authors popup.nrat_date 2020-04-02 Close
