Q.A saturated solution of $KNO_3$ is used to make a salt bridge because:

Velocity of

K^+

is greater than

NO_3^-

Velocity of

NO_3^-

is greater than

K^+

Velocities of both

K^+

and

NO_3^-

are nearly same

KNO_3

is highly soluble in water

The correct solution involves applying the fundamental concept to derive the final value step by step...
