Answer to Question #145485 in General Chemistry for Kert Bisnar

Question

Why aqueous silver nitrate is not used in a salt bridge when connecting half-cell containing Zn and 1.00 mo1L ZnCl2(aq) to another half-cell?

Answer 1

This is because Silver ions (Ag⁺) will react with the Chloride ions (Cl^-) to form a precipitate therefore, consuming the free ions of Silver ions, impairing the flow of current. Accordingly, the activities within the cell stops.

Ag⁺_(aq)+Cl^-_(aq)=AgCl_(s)
