    Saturated solution of \[KN{{O}_{3}}\] is used to make ?salt-bridge? because                                         [IIT Screening 2002]

    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)                 \[KN{{O}_{3}}\]is highly soluble in water

    Correct Answer: C

    Solution :

                    Velocities of both \[{{K}^{+}}\] and \[NO_{3}^{-}\] are nearly the same in \[KN{{O}_{3}}\] so it is used to make salt-bridge.
