Solvation Behavior of Glycine, l-Alanine, and l-Valine in Aqueous Solutions of Triammonium Citrate at Different Temperatures with Reference to Speeds of Sound Measurements

The speeds of sound measurements are carried out for investigating the interactions of glycine, l-alanine, and l-valine in (0.2,0.4,0.6,and0.8)mol·kg-1\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$(0.2, 0.4, 0.6, \hbox { and } 0.8)\hbox { mol}{\cdot }\hbox {kg}^{-1}$$\end{document} solutions of triammonium citrate (TAC) at T=(288.15,298.15,308.15,and318.15)K\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$T = (288.15, 298.15, 308.15, \hbox { and } 318.15)\hbox { K}$$\end{document}.

The pair and triplet interaction coefficients have also been calculated. The results have been discussed in terms of prevailing interactions between amino acids and TAC solutions.
