Saturated solution of \( \mathrm{KNO}_{3} \) is used to make salt bridge because
\( \mathrm{P} \)
(A) velocity of \( \mathrm{K}^{+} \)is greater than that of \( \mathrm{NO}_{3}^{-} \)
W
(B) velocity of \( \mathrm{NO}_{3}^{-} \)is greater than that of \( \mathrm{K}^{+} \)
(C) velocities of both \( \mathrm{K}^{+} \)and \( \mathrm{NO}_{3}^{-} \)are nearly the same
(D) \( \mathrm{KNO}_{3} \) is highly soluble in water
