Question

Lfef Vapor-pressure measurements give the mean ionic activity coefficient of CdCl2 in a 0.100 mol/kg aqueous Cacl2 solution at 25°C and 1 bar as v. =0.228. Find Eo and E at 25°C and 1 bar for the cell C'S Cals) CdCl2 (@q, Q100 mol/kg) II AgCl(s) I Ag(s) By convention, the left-hand electrode involves oxidation Scanner
