For given voltaic cell with given half cells, the [ Pb 2+ ] has to be calculated when [ Mn 2+ ] =1 .4 and E cell = 0 .44 V Concept Introduction: An electrochemical cell is a device in which a redox reaction is used to convert chemical energy into electrical energy. Such device is also known as the galvanic or voltaic cell. Galvanic cell consists of two half-cells. The redox reaction occurs in these half-cells. The half-cell in which the reduction reaction occurs is known as the reduction half-cell, whereas the half-cell in which the oxidation reaction occurs is known as the oxidation half-cell. Anode: The electrode where the oxidation occurs is called as an anode. It is a negatively charged electrode. Cathode: The electrode where reduction occurs is called as a cathode. It is a positively charged electrode. Oxidation: The gain of oxygen or the loss of hydrogen or the loss of an electron in a species during a redox reaction is called as oxidation. Reduction: The loss of oxygen or the gain of hydrogen or the gain of an electron in a species during a redox reaction is called as reduction. The Standard Gibb’s free energy change and the standard cell potential are related as followed: Δ ° G = -nFE ° cell n - Number of electrons involved per equivalent of the net redox reaction in the cell F - Faraday’s Constant (96500 C) E ° cell - Standard cell potential.
