MCQ

Saturated solution of $KN{O_3}$ 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 ${K^ + }$
✓
Velocities of both ${K^ + }$and $NO_3^ - $ are nearly the same
D
$KN{O_3}$is highly soluble in water

✓

Answer

Correct option: C.

Velocities of both ${K^ + }$and $NO_3^ - $ are nearly the same

c
(c)Velocities of both ${K^ + }$ and $NO_3^ - $ are nearly the same in $KN{O_3}$ so it is used to make salt-bridge.
