Problem

Saturated solution of

\text{KNO}_3

is used to make salt bridge because : (IIT 2001) a. velocity of

\text{K}^+

is greater than that of

\text{NO}_3^-

b. velocity of

\text{NO}_3^-

is greater than that of

\text{K}^+

c. velocity of both

\text{K}^+

and

\text{NO}_3^-

are nearly the same d.

\text{KNO}_3

is highly soluble in water
