Abstract

Gibbs free energy is a measure of relative stability among substances. Since the nature of the ions in aqueous solution is diverse, their thermodynamic data at extensive experimental conditions is scarce. In this work, the calculation procedure was introduced to obtain the absolute and conventional standard molar enthalpies and entropies of hydration of ions from the standard enthalpies and entropies of formation of hydrated ions. The application of correspondence principle to estimate thermodynamic data at high temperature was explained.

자유에너지는 물질의 상대적인 안정도를 나타낸다. 수용액에 존재하는 이온의 종류는 다양하고 실험조건이 광범위하므로 열역학 자료가 부족하다. 이온의 표준생성엔탈피와 엔트로피로부터 표준수화엔탈피와 표준수화엔트로피의 절대값과 상대값을 구하는 방법을 설명하였다. 또한 대응원리를 이용하여 고온에서 열역학 자료를 추산하는 방법을 설명하였다.
