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

Velocity of both `K^(+)` and `NO_(3)^(-)` are nearly the same

D

`HNO_(3)` is highly soluble in water

Text Solution

Verified by Experts

The salt used to make 'salt-bridge' must be such that the ionic mobility of cation and anion are of comparable order so that they can keep the anode and cathode half cells neutral at all ti,es `KNO_3` is used because velocities of `K^(+)` and `NO_3^(-)`ions are nearly same.
