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 the same
• D. $KN{O}_3$ is highly soluble in water

Answer 1

The correct option is C velocity of both $K^{+}$ and $N{O}_3^{-}$ are nearly the same

Since $K^{+}$ and $N{O}_3^{-}$ are having the same Transport Number
