Electrolysis :: Papers

In chemistry, the production of chemical substance pitchs by transeunt an electric current through a solution or resolve salt (the electrolyte), resulting in the migration of ions to the electrodes positive ions (cations) to the negative electrode (cathode) and negative ions (anions) to the positive electrode (anode). During electrolysis, the ions fight down with the electrode, either receiving or giving up electrons. The resultant atoms may be liberated as a gas, or deposited as a satisfying on the electrode, in amounts that are proportional to the amount of current passed, as discovered by English chemist Michael Faraday. For instance, when acidified water is electrolysed, hydrogen ions (H+) at the cathode receive electrons to form hydrogen gas hydroxide ions (OH-) at the anode spend up electrons to form oxygen gas and water. One application of electrolysis is electroplating, in which a solution of a salt, such as eloquent process (AgNO3), is used and the object to be plated acts as the negative electrode, thus attracting silver ions (Ag+). Electrolysis is used in many industrial processes, such as culture metals for vehicles and ships, and refining bauxite into aluminium it also forms the basis of a number of electrochemical analytical techniques, such as polarography. Faradays laws ============== Three laws of electrocharismatic induction, and two laws of electrolysis, exclusively proposed originally by English scientist Michael Faraday Induction (1) a changing magnetic field induces an electromagnetic force In a conductor (2) the electromagnetic force is proportional to the rate of change of the field (3) the direction of the generate electromagnetic force depends on the orientation of the field. Electrolysis (1) the amount of chemical change during electrolysis is proportional to the charge passing through the liquid (2) the amount of chemical change produced in a substance by a tending(p) amount of electricity is proportional to the electrochemical equivalent of that substance. Faradays constant ================== uninterrupted (symbol F) representing the electric charge carried on one mole of electrons.
