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

A

velocity of `K^(+)` is greater than that of `NO_(3)^(-)`

B

velocity of `NO_(3)^(-)` is greater than that of `K^(+)`

C

Velocities of both `K^(+)` and `NO_(3)^(-)` are neraly the same

D

`KNO_(3)` is highly soluble in water.

Text Solution

Verified by Experts

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