Electrolysis :: Papers

In chemistry, the production of chemical substance changes by passing an electric received through a solution or molten salt (the electrolyte), resulting in the migration of ions to the electrodes validating ions (cations) to the negative electrode (cathode) and negative ions (anions) to the positive electrode (anode). During electrolysis, the ions react with the electrode, either receiving or giving up electrons. The resultant atoms may be liberated as a gas, or deposited as a solid on the electrode, in heart and souls that are proportional to the amount of current passed, as discovered by English chemist Michael Faraday. For instance, when acidified water is electrolysed, heat content ions (H+) at the cathode receive electrons to form hydrogen gas hydroxide ions (OH-) at the anode give up electrons to form oxygen gas and water. One lotion of electrolysis is electroplating, in which a solution of a salt, such as ash grey nitrate (AgNO3), is used and the object to be plated acts as the negative electrode, therefore attracting silver ions (Ag+). Electrolysis is used in many industrial processes, such as coating metals for vehicles and ships, and refining bauxite into aluminium it also forms the basis of a phone number of electrochemical analytical techniques, such as polarography. Faradays laws ============== Three laws of electromagnetic induction, and both laws of electrolysis, all proposed originally by English scientist Michael Faraday Induction (1) a ever-changing magnetic field induces an electromagnetic force In a director (2) the electromagnetic force is proportional to the rate of change of the field (3) the bearing of the induced 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 g iven amount of electricity is proportional to the electrochemical equivalent of that substance. Faradays ceaseless ================== Constant (symbol F) representing the electric charge carried on one mole of electrons.
