The W-cell consists of a cadmium amalgam anode and a mercury-mercurous sulfate cathode with a saturated cadmium sulfate solution as the electrolyte. This cell has been commonly used as a voltage standard in laboratories, replacing the previous standard C-cell. The voltage of this cell is 1.0183 V at 293 K and the temperature coefficient ? ?? dE??? dT a. Write down a cell diagram for the W-cell. b. Write down the half cell and the full cell reactions. c. Calculate ?G at 20 oC for the cell reaction. d. Calculate ?S at 20 oC for the cell reaction. of the cell is –4.06x10-5 V K-1. p e. The C-cell has an EMF defined by [1.434 - 0.0012 (T - 15)] Volts, where T is in oC. Calculate the temperature coefficient of the C-cell and suggest why the W-cell is better suited as a voltage standard than the C-cell. f. Explain why when using standard cells no appreciable current should be drawn
