Abstract: This paper reports our studies on HCl+NaCl+PrOH+H_2O system by mesns of emf measurements of the cell without liquid junction as type (A)
Pt, H_2 (latm) |HCI (m_A), NaCl (m_B), PrOH(x), H_2O(1-x)| AgCl-Ag (A)
at constant total ionic strengths I=0.1, 0.5, 1.0, 2.0 and 3.0 mol kg~(-1), at 298.15 K, where m_A and m_B are the molalities of HCl and NaCl, respectively, x is the molar fraction of PrOH in mixed solvents, x=0.05.
The results show that HCI approximately follows Harned's Rule from I=0.1 to 3.0 mole kg~(-1)...
