E) The salt bridge maintains electroneutrality throughout the cell. D) Galvanic cells are composed of two half-cells connected by salt bridge. C) Electrons move toward more negative electrical potential. Genereal Chemistry: Principles and Modern Applications 9th Ed. B) Oxidation occurs at the anode and reduction occurs at the cathode. Harwood, William, Herring, Geoffrey, Madura, Jeffry, and Petrucci, Ralph, General Chemistry: Principles and Modern Applications, Ninth Edition, Upper Saddle River,New Jersey, Pearson Prentice Hall, 2007.“ Descriptive Principles of Chemistry”, C.V. In any electrochemical cell the anode is the electrode at which oxidation occurs. “Chemistry: The Central Science” Fifth Edition, Prentice-Hall, Inc. “Chemistry: The Central Science” Third Edition, Prentice-Hall, Inc. “Chemistry: The Study of Matter and Its Changes”, John Wiley & Sons Inc 1993 The lack of concentrations indicates solutions are under standard conditions (i.e., 1 M) Define the terms: oxidation, reduction, standard reduction potential, anode, and cathode. Corrosion requires an anode and cathode to take place. Separate changes in phase by | and indicate the the salt bridge with ||. Science Chemistry Chemistry questions and answers 1. Reducing agents and oxidizing agents are the ones responsible for corrosion, which is the 'degradation of metals as a result of electrochemical activity'. The anode always goes on the left and cathode on the right.
