Saturated solution of KNO3 is used to make salt-bridge because:
- velocity of K+ is greater than that of \(\mathrm{NO}_{3}^{-}\) ion.
- velocity of \(\mathrm{NO}_{3}^{-}\) is greater than that of K+ion.
- velocities of both K+ and \(\mathrm{NO}_{3}^{-}\) are nearly the same.
- KNO3 is highly soluble in water.
Answer
(C) velocities of both K + and NO _ 3 ^ - are nearly the same.
