Electrochemistry Wikipedia

Electrochemistry is the branch of physical chemistry that studies the relationship between electricity, as a measurable and quantitative phenomenon, and identifiable chemical change, with either electricity considered an outcome of a particular chemical change or vice versa.These reactions involve electric charges moving between electrodes and an electrolyte (or ionic species in a solution).

Electroplating Definition Process & Uses of Chemistry

What is Electroplating? Electroplating is basically the process of plating a metal onto the other by hydrolysis mostly to prevent corrosion of metal or for decorative purposes.. The process uses an electric current to reduce dissolved metal ions to develop a lean coherent metal coating on the electrode.

What Is Electroplating and How Does It Work? ThoughtCo

Jun 27, 2019 · Electroplating Example. A simple example of the electroplating process is the electroplating of copper in which the metal to be plated (copper) is used as the anode, and the electrolyte solution contains the ion of the metal to be plated (Cu 2+ in this example). Copper goes into solution at the anode as it is plated at the hode.
