Calculate the half cell potential of a reaction Ag_(2)S + 2e rarr 2Ag + S^(2-) in a solution beffered at pH = 3 and also saturated with 0.1 M H_(2)S. K_(1) and K_(2) for H_(2)S are 10^(-8) and 1.1 xx 10^(-8) and 1.1 xx 10^(-13) respectively. (K_(SP_(Ag_(2)S)) = 2 xx 10^(-49), E_(Ag^(+)//Ag)^(@) = 0.8 V) |
