## Calculate the emf at 25°C of the cell represented by the following reaction : Zn(s) + CdS04(aq) = Cd(s) + ZnS04(uq) The activities of CdSO,(aq) and ZnS04(aq) are 7.0~10~ and3.9xlO3, respectively, and cadmium is in the form of alloy with more noble metal (acd = 0.6).

1.Calculate the emf at 25°C of the cell represented by the following reaction : Zn(s) + CdS04(aq) = Cd(s) + ZnS04(uq) The activities of CdSO,(aq) and ZnS04(aq) are 7.0~10~ and3.9xlO3, respectively, and cadmium is in the form of alloy with more noble metal (acd = 0.6). The standard emf of the cell at 25°C is 0.36 volts.

1. Write the electrode reactions and the cell reactions for the following galvanic cells, and calculate the standard emf s of the cells at 25°C. Determine the positive electrodes : 1) cu I CuCl,(aq) I Cl*&), Pt 2) Ag, AgCl I HCl(aq) IlHWq) I A@r, Ag
