Vedclass · Answer

(C) salt bridge requires an electrolyte where the transport numbers of the cation and anion are nearly equal. Since the ionic velocities of $K^+$ and $NO_3^-$ are approximately the same,$KNO_3$ is used in the salt bridge to maintain electrical neutrality without creating a significant liquid junction potential.

$A$ concentrated solution of $KNO_3$ is used in the preparation of a salt bridge because:
