The diffusion coefficient for \(\mathrm{NO}_{3}{ }^{-}\)ion is bigger than the diffusion coefficient for \(\mathrm{Na}^{+}\) ion. Consider measuring the electrochemical cell potential in which a salt bridge is used between the reference solution containing \(3 \mathrm{M} \mathrm{NaNO}_{3}\) and a sample containing \(0.1 \mathrm{M} \mathrm{NaNO}_{3}\) supporting electrolyte solution. Explain whether there will be a junction potential and, if so, whether the cell potential with the junction potential will appear more positive or more negative than without it.
