Équilibrer des réactions redox
Electrochemistry is the science involved in the interconversion of electrical and chemical reactions. Such reactions are called reduction-oxidation,…
Force électromotrice
Electricity is generated by either electrons or ions flowing through a solution or a conducting medium. This flow of electrons or specifically…
Cellules galvaniques/voltaïques
Spontaneous Chemical Reactions Spontaneous redox reactions occur abundantly in nature. The chemical reaction occurring in a disposable AA battery…
Potentiels standard d'électrode
On comparing the reactivity of silver and lead, it is observed that the two ionic species, Ag+ (aq) and Pb2+ (aq), show a difference in their redox…
Potentiel de cellule et énergie libre
Thermodynamics of a Redox Reaction Thermodynamics is the branch of physics dealing with the relationship between heat and other forms of energy. In…

Nonstandard Reaction Conditions The interconnection between standard cell potentials and various thermodynamic parameters such as the standard free…
Piles de concentration
A concentration cell is a type of a  voltaic cell constructed by connecting two almost identical half-cells, both based on the same…
Piles et piles à combustible
A battery is a galvanic cell that is used as a source of electrical power for specific applications. Modern batteries exist in a multitude of forms…
Corrosion
The degradation of metals due to natural electrochemical processes is known as corrosion. Rust formation on iron, tarnishing of silver, and the…
Électrolyse
In a galvanic cell, the electrical work is done by a redox system on its surroundings as electrons produced by the spontaneous redox reactions are…
Metal Corrosion and the Efficiency of Corrosion Inhibitors in Less Conductive Media
Material corrosion can be a limiting factor for different materials in many applications. Thus, it is necessary to better understand corrosion…
Determination of Thermodynamic Properties of Alkaline Earth-liquid Metal Alloys Using the Electromotive Force Technique
A novel electrochemical cell based on a CaF2 solid-state electrolyte has been developed to measure the electromotive force (emf) of binary alkaline…
Characterizing Electron Transport through Living Biofilms
Here we demonstrate the method of electrochemical gating used to characterize electrical conductivity of electrode-grown microbial biofilms under…
