The passage of an electric current through an Electrolyte, causing the migration of the positively charged ions to the negative electrode (cathode) and the negatively charged ions to the positive electrode (anode) ADVANCE \x 540
the process of breaking down a chemical compound into its component elements, by passing an electric current through it Electrolysis is not an equilibrium process; in fact, it is intentionally driven far from equilibrium to cause as much breakdown of the compound as possible In electrolysis, some atoms are oxidized, while others are reduced
The act or process of chemical decomposition, by the action of electricity; as, the electrolysis of silver or nickel for plating; the electrolysis of water
An electrochemical reaction causing a black stain normally found around metal fixtures or on the plaster It is caused by two dissimilar metals being plumbed together or from an improper electrical grounding of pool equipment or lights Electrolysis also means the decomposition of water and other inorganic compounds in aqueous solution by means of electricity Chlorine generators use this principle to produce chlorine from salt in the water
An electric current is passed through a solution containing dissolved metals, causing the metals to be deposited onto a cathode Electrolytic refining - The process of purifying metal ingots that are suspended as anodes in an electrolytic bath, alternated with refined sheets of the same metal which act as starters or cathodes EM survey - A geophysical survey method which measures the electromagnetic properties of rocks Environmental impact study - A written report, compiled prior to a production decision, that examines the effects proposed mining activities will have on the natural surroundings Epithermal deposit - A mineral deposit consisting of veins and replacement bodies, usually in volcanic or sedimentary rocks, containing precious metals or, more rarely, base metals
Electrolysis is the process of passing an electric current through a substance in order to produce chemical changes in the substance. Process in which electric current passed through a substance causes a chemical change, usually the gaining or losing of electrons (see oxidation-reduction). It is carried out in an electrolytic cell consisting of separated positive and negative electrodes (anode and cathode, respectively) immersed in an electrolyte solution containing ions or in a molten ionic compound. Electric current enters through the cathode; positively charged cations travel to it and combine with electrons. Negatively charged anions give up electrons at the anode. Both thus become neutral molecules. Electrolysis is used extensively in metallurgy to extract or purify metals from ores or compounds and to deposit them from solution (electroplating). Electrolysis of molten sodium chloride yields metallic sodium and chlorine gas; that of a strong solution of sodium chloride in water (brine) yields hydrogen gas, chlorine gas, and sodium hydroxide (in solution); and that of water (with a low concentration of dissolved sodium chloride or other electrolyte) yields hydrogen and oxygen
The process in which an electric current flowing through a water solution of a chemical breaks that compound up into its component parts Chlorine is produced by electrolysis of brine (salt dissolved in water)
the passage of an electric current through a substance in order to cause a chemical change; the use of electric energy to produce an oxidation-reduction process
Breaking a chemical compound down into its elements by passing a direct current through it Electrolysis of water, for example, produces hydrogen and oxygen
removing superfluous or unwanted hair by passing an electric current through the hair root lysis of a bond produced by the passage of an electric current
The process used for refining precious and other metals in which an electric current passes through an electrolyte (chemical solution) from anode to cathode Impure metal dissolves at the anode and pure metal is deposted to the cathode
