    Chemistry Essay: Electrochemical Cells By John Williams An electrochemical cell is s cell in which chemical energy in a redox reaction is converted to electrical energy. It consists of two half cells connected internally by a salt bridge and externally by wires. A hydrogen half cell is the standard electrode and all comparisons of the other half cells are made against this half cell which has an E( value of zero volts. The E( values of other half cells are obtained by measuring the total emf (electromotive

    Experiment 4: Conductivity of electrolyte solutions (Dated: October 29‚ 2009) I. INTRODUCTION Pure water does not conduct electricity‚ but any solvated ionic species would contribute to conduction of electricity. An ionically conducting solution is called an electrolyte solution and the compound‚ which produces the ions as it dissolves‚ is called an electrolyte. A strong electrolyte is a compound that will completely dissociate into ions in water. Correspondingly‚ a weak electrolyte dissolves
