Abstract

In this paper the results of compressibility of aqueous solutions of amino acids in water and in aqueous HCl and NaOH solutions at 25 °C are presented. The effect of the charged protonated amino groups and deprotonated carboxylic groups on the hydration number was tested. The idea of additivity of the hydration number with the constituents of the solute molecule was successfully applied and discussed.

摘要

本文介绍了在 25°C 下，氨基酸在水中以及在盐酸和氢氧化钠水溶液中的压缩性的研究结果。测试了带电荷的质子化氨基和去质子化羧酸基团对水合数的影响。成功地应用和讨论了溶质分子组成部分的水合数可加性的思想。
