Saturated solution of KNO3 with agar-aga...

Saturated solution of `KNO_3` with agar-agar 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

`KNO_3` is highly soluble in water
