The upper graph shows the current density as function of the overpotential η . The anodic and cathodic current densities are shown as j a and j c, respectively for α=α a =α c =0.5 and j 0 =1mAcm −2 (close to values for platinum and palladium).
A well-known electrosynthesis is the Kolbe electrolysis, in which two carboxylic acids decarboxylate, and the remaining structures bond together:; A variation is called the non-Kolbe reaction when a heteroatom (nitrogen or oxygen) is present at the α-position.
Electrochemistry also has important applications in the food industry, like the assessment of food/package interactions, [36] the analysis of milk composition, [37] the characterization and the determination of the freezing end-point of ice-cream mixes, or the determination of free acidity in olive oil.
Bipolar electrochemistry scheme. In electrochemistry, standard electrode potential, or , is a measure of the reducing power of any element or compound.The IUPAC "Gold Book" defines it as; "the value of the standard emf (electromotive force) of a cell in which molecular hydrogen under standard pressure is oxidized to solvated protons at the left-hand electrode".
During the early development of electrochemistry, researchers used the normal hydrogen electrode as their standard for zero potential. This was convenient because it could actually be constructed by "[immersing] a platinum electrode into a solution of 1 N strong acid and [bubbling] hydrogen gas through the solution at about 1 atm pressure".

From December 2011 to December 2012, if you bought shares in companies when Nancy McKinstry joined the board, and sold them when she left, you would have a 20.1 percent return on your investment, compared to a 13.6 percent return from the S&P 500.
Electrochemical engineering is the branch of chemical engineering dealing with the technological applications of electrochemical phenomena, such as electrosynthesis of chemicals, electrowinning and refining of metals, flow batteries and fuel cells, surface modification by electrodeposition, electrochemical separations and corrosion.
