KCl cannot be used as a salt bridege for the cell Cu(s)|CuSO_(4)(aq.)||AgNo_(3)(aq.)|Ag(s) because |

Answer» `Cl_(2)` gas is evolved The cell terminals are at the extreme ends in this cell notation. and a single cerical bar indicates a phase boundary-sat between a SOLID terminal and the electrode solution. for example, the zinc electode is a solild while the `Zn^(2+)` ions (form `ZnSO_(4)`) are in solution. thus, we draw a line between `Zn` and `Zn^(2+)` to show the phase boundries. Note that there is also a line between the `ZnSO_(4)` solution and the `KCl` solution in the salt bridge because these two solutions are not mixed physically and therefore constitute two separate phases. |
