Additional Problems:

1.  Using the solubility product for Ag2SO3 is 1.5 x 10-14 and the Eš for the reduction of Ag+ to Ag(s) (see appendices), determine

the Eš for the reaction Ag2SO3(s) + 2e- ↔ 2Ag(s) + SO32-.

 

2.  An electrochemical cell (see notation and diagram below) is made to determine the concentration of tin (Sn2+) in an industrial process stream:

SnO2(s)|Sn2+ (X M), HNO3 (0.10 M)|| ‌NaCl (0.10 M)|Ag(s), AgCl(s)

If the cell potential is measured (connecting the Ag/AgCl electrode to the positive end of a voltmeter) and found to be 0.380 V,

determine the concentration of tin in the cell.
