Question

Saturated solution of $ KN{{O}_{3}} $ is used to make salt bridge because

• A. velocity of $ {{K}^{+}} $ is greater than that of $ N{{O}^-_{3}} $
• B. velocity of $ N{{O}_{3}^-} $ is greater than that of $ {{K}^{+}} $
• C. velocity of both $ {{K}^{+}} $ and $ N{{O}_{3}^-} $ are nearly same
• D. $ KN{{O}_{3}} $ is soluble in water

Answer 1

Answer: (C)

Velocity of both $ {{K}^{+}} $ and $ NO_{3}^{-} $ is nearly the same.
