Saturated solution of `KNO_3` with agar-agar is used to make 'salt bridge' because:

KNO_(3) is used to make salt bridge because:

Saturated solution of KNO_(3) is used to make 'salt bridge' because (A) velocity of K^(+) is greater than that of NO_(3)^(-) (B) velocity of NO_(3)^(-) is greater than that of K^(+) (C) velocities of both K^(+) and NO_(3)^(-) are nearly the same (D) KNO_(3) is highly soluble in water

Saturated solution of KNO_(3) is ued to make 'salt - bridge' because ,

KCl is used in salt bridge because:
