Question

The reason why saturated solution of $KNO_{3}$ is used to make ‘salt-bridge’

• 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

Answer 1

Answer: (C)

Velocities of both $K^{+}$ and $NO_{3}^{-}$ are nearly the same in $KNO_{3}$ so it is used to make salt-bridge.
