A standard solution of `KNO_(3)` is used to make salt bridge, because

A

Velocity of `K^(+)` is greater than 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

`KNO_(3)` is highly soluble in water

Text Solution

Verified by Experts

The correct Answer is:
C
(c ) Velocities (ionic mobilities) of `K^(+)` and `NO_(3)^(-)` ions are nearly the same.
