混合溶剂中混合电解质活度系数的研究——HCl+NaCl+PrOH+H_2O体系,298.15K

电动势法是测定混合电解质活度系数时常用的主要方法,曾用这种方法对混合电解质水溶液活度系数作过火量的研究。可是,在有机溶剂和水的混合溶剂中混合电解质的电动势数据和活度系数数据却很少。Akerlof等人在这方面进行了开创性的研究工作,他们在恒定总     

混合溶剂中混合电解质活度系数的研究——HCl+NaCl+PrOH+H2O体系, 298.15 K

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)...
