THE STUDY OF MILLIVOLT EMF STANDARD CELLS
Qu Jin(Department of Chemistry)
The emf of the cell: Cd(Pb, Hg)|CdSO_4·8/3 H_2O(S)|CdSO_4(saturated)|CdSO_4·8/3 H_2O(S)|Cd(Hg) is approximately equivalent to 1.015 mV at 20℃. The above cell has a high emf stability. This paper deals with the determination of emf-temperature equation, the internal resistance and the capability to recove their initial emf after charging or discharging and emf-temperature hysteresis of the cell.
