Electrochemistry (ElectroChemistry) Electrochemistry is a chemical reaction a study that resulted in electricity. The chemical reaction produces electricity using an electron transfer reaction and chemical criteria are divided into 2 categories.1. the reaction with transfer e-called the principal's response ok (Redox Reaction)2. non-reaction to dump e-bed reaction called Board ok (Nonredox Reaction)The principal's response ok (Redox Reaction or Oxidation-reduction Reaction)The principal reaction means ok just manner on exposures and e-Sample When the metal plates, copper (Cu) dipped in a solution of AgNO3 was found that sheet metal Cu has a solid mix of gray and white came to the island to bring tap to find metals Cu corrosion caused sections of colors, AgNO3 solution will change from blue to colorless transparent.The changes that occurred in this description of the metal copper was born. Corrosion is metal, copper (Cu) Born to lose an electron to become Cu2 +, Ag + and blue get electrons to become Ag (silver metal) comes under the copper sheet metal. Reactions that occur. Cell electrochemistry Because of that, the substance that gives the pesticides and e-e-sense direct is unable to render the electricity that occurs. So if you want to have electricity going to wire the electrical connection of the electrode during half the cells, e-and e-pick cells and half with a volt meter and half the salt bridge between the two cells. The standard electrical potential (E°)One half of a standard cell is used to compare the ability to receive e-of half the cells use hydrogen cell half written by Pt (s) | | + H2 (1atm) H (1M) and given the potential of the standard hydrogen electrode conditions (25° C, 1atm) The Wole lotEo H2 = 0.00 VoltStandard electric potential measurement of any electric cell by applying half-standard half cell with hydrogen cells and electrode must be dipped in concentrated aqueous solution 1 Molar.
