Unformatted text preview: Salt bridges allow the flow of ions between the oxidation and reduction vessels while keeping them separated. 3) (5 points) Explain why the galvanic cell below doesnt work. The net reaction is spontaneous but a little current flows through the circuit because Ag + ions are not forced to be reduced at the Ag electrode. The Ag + ions in solution can react directly at the Cd(s) surface, giving the same net reaction with no flow of electrons through the external circuit....
