Electrochemical reactions are those reactions either caused or accompanied by the transfer of an electric current and most often involve the transfer of electrons, i.e. electrical current, between two substances; one a solid and the other a liquid. An electrochemical reaction usually is the combination of two different types of reactions; one an oxidation reaction which produces electrons and one a cathodic reaction that consumes the electrons. The oxidation reactions occur on an anode electrode and the reduction reactions occur on a cathodic electrode. The electrode of the reaction of interest is usually refereed to as the working electrode and the other electrode is refereed to as the counter electrode. Examples of the electrochemical reactions are electro-deposition of metals such as copper, electro-dissolution of minerals and metals such as corrosion of steel, and cementation (i.e. precipitation of a more noble metal such as gold by sacrificing a less noble metal such as zinc).

电化学反应是由电流的转移引起或伴随的那些反应，并且通常涉及两种物质之间的电子（即电流）的转移;一种是固体，另一种是液体。电化学反应通常是两种不同类型的反应的组合;一种是产生电子的氧化反应，另一种是消耗电子的阴极反应。氧化反应发生在阳极电极上，还原反应发生在阴极电极上。感兴趣的反应的电极通常被称为工作电极，另一个电极被称为反电极。电化学反应的实例是金属（例如铜）的电沉积、矿物和金属（例如钢的腐蚀）的电溶解以及渗碳（即，通过牺牲较不贵的金属（例如锌）来沉淀较贵的金属（例如金））。
