Question

Saturated solution of KNO3 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) KNO3 is highly soluble in water

One of the requirement for electrolyte used in salt-bridge is, both cation and anion must have comparable size so that they migrate towards electrodes of opposite polarity at comparable speeds.

Q. Saturated solution of $K N O_{3}$ is used to make -salt-bridge- because

velocity of $K^{+}$ is greater than that of $N O_{3}^{-}$

velocity of $N O_{3}^{-}$ is greater than that of $K^{+}$

velocities of both $K^{+}$ and $N O_{3}^{-}$ are nearly the same

$K N O_{3}$ is highly soluble in water

Q. Saturated solution of KNO3​ is used to make -salt-bridge- because

velocity of K+ is greater than that of NO3−​

velocity of NO3−​ is greater than that of K+

velocities of both K+ and NO3−​ are nearly the same

KNO3​ is highly soluble in water
