Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Abstract The kinetics of the electrochemical oxidation–reduction of silver in aqueous solutions of sodium nitrate was studied by potentiometry. The effect of the electrolyte concentration and temperature and sweep rate on the electrochemical behavior of silver was studied. To characterize the mechanism of silver electrooxidation, the following kinetic parameters were calculated: ion transport number (αn), diffusion coefficient (D), heterogeneous rate constant of the electrode process (Ks), and effective activation energy of the process (Eef). The data obtained may be of interest to specialists in the field of electrochemistry.
