Why do the liquid junctions potentials 0.1 M HCl | 0.1 M KCl and 0.1 M NaOH
Question:
Why do the liquid junctions potentials 0.1 M HCl | 0.1 M KCl and 0.1 M NaOH | 0.1 M KCl have opposite signs in Table 15-2? Why is the junction potential for 0.1 M NaOH | 0.1 M KCl so much more negative than 0.1 M NaOH | KCl (saturated)?
