330033 A salt bridge may contain:

1 a saturated solution of \({\rm{KCl}}\) and agar-agar
2 a saturated solution of \({\rm{KN}}{{\rm{O}}_{\rm{3}}}\) and agar-agar
3 a saturated solution of \({\rm{N}}{{\rm{H}}_{\rm{4}}}{\rm{N}}{{\rm{O}}_{\rm{3}}}\) and agar- agar
4 All of these

330034 The function of a salt bridge is to

1 maintain electrical neutrality of both half cells.
2 increase the cell potential at the positive electrode.
3 decrease the cell potential at the negative electrode.
4 eliminated the impurities present in the electrolyte.
