摘要

本文用提出的折射法研究了KCl、KBr、KI、HCl、LiCl、CsCl、NaCl等电解质的稀水溶液中离子(K+与Cl-、K+与Br-、K+与I-、H+与Cl-、Li+与Cl-、Cs+与Cl-、Na+与Cl-)的水化次数。进一步研究了聚乙二醇(PEG-6000)对KCl和KBr水溶液中离子水化过程的影响。结果表明,当聚合物被引入到溶液中时,离子的水化数减少,这显然是由于PEG氧原子在与水分子相互作用时与离子竞争的作用。

Hydration Processes in HCl and Aqueous Salt Solutions
In this work, the number of hydration of ions (K+ and Cl-, K+ and Br-, K+ and I-, H+ and Cl-, Li+ and Cl-, Cs+ and Cl-, Na+ and Cl-) in dilute aqueous solutions of some electrolytes of KCl, KBr, KI, HCl, LiCl, CsCl, and NaCl was studied by the proposed refractometric method. Further, the effect of polyethylene glycol (PEG-6000) on the hydration processes for ions in aqueous solutions of KCl and KBr was studied. It turned out that when the polymer is introduced into the solution, the hydration numbers of ions decrease, which is apparently due to the role of the PEG oxygen atom competing with ions in interaction with water molecules.
