... (M - P2) Transition metals (SS - P3) * Chemical equilibrium (A -P2) Electrochemical cells (SS - P3) * Moles, concentration, Complex ions (SS - P3) volume (EL, DF,M,A - P1 & 2) Colorimetry (SS - P3) * Volumetric analysis (EL,DF - P1) Electrode potentials (SS - P3) * Half equations (M,A - P2) Nernst equation * Oxidation numbers (M - P2) Ion Exchange (AA - P4) * Serial dilution Electrochemical analysis Electrochemistry is based solely on redox reactions of the transfer of electrons, from the less positive to the more positive terminal. An electrochemical cell is composed of two half-cells connected by electric wires and a salt bridge. A half- cell simply consists of a salt solution of a particular metal ion and a strip of the same elemental metal dipped into the solution. These are connected by electric wires to a high resistance voltmeter and a salt bridge consisting of a ...
