Abstract The following paper examines the chemical process and applications of Brine Electrolysis in an industrial scale and how setting up a brine electrolysis plant in Jeju city, Jeju island, South Korea will ultimately contribute to the safety and well-being of the region. The expected result is highly beneficial for both the host of the project and for the residents of Jeju. The host of the project has a variety of products that achieve both monetary profit and the health of the UNESCO world heritage site. Brine is water containing a high concentration of salt1, and explicitly a saturated solution of Sodium chloride in the following project, supplied from solution mining of rock salt deposits, or the crystallisation of seawater.

The chemical process can be performed using simple apparatus in the laboratory. A beaker, a saturated solution of sodium chloride, two carbon electrodes and a power supply is to be prepared. The two electrodes, constructed of carbon, are to be connected to a power supply and each of them to be submerged in a container filled with a saturated solution of sodium chloride; not fully, but in significant amount. In the saturated sodium chloride solution, which is the electrolyte of the process, there are positive Sodium ions, Na+, and negative Chlorine ions, Cl-. In the water, there are positive hydrogen ions, H+, and negative Hydroxide ions, OH-. When the power supply is switched on and the current flows, the anode, the positive electrode, attracts negative ions, which specifically in this chemical process are chlorine ions. Likewise, the cathode, the negative electrode, attracts positive ions, or explicitly hydrogen ions.

Here, hydrogen undergoes oxidation instead of sodium(metal) because hydrogen fall under sodium in the reactivity series. Oxidation occurs in the anode and reduction occurs in the cathode to produce diatomic gas molecules. Physically, this process is to be seen as effervescence forming at each electrode, which demonstrate the production of hydrogen and chlorine gas.
