Department of Chemistry, Kurukshetra University, Kurukshctra-136 119. India E-mail : palchem@sify.com Manuscript received 27 July 2004 The densities and sound speeds of L-glycine in aqueous (CH3)4Nl, NaBr and NaI are reported at 298.15 K. These data are used to derive apparent molar volumes \(V_\phi\), and compressibilities \(K_{\phi,S}\)· Partial molar volumes \(V^0_\phi\) and partial molar adiabatic compressibilities \(K^0_{\phi,S}\) of L-glycine at infinite dilution were evaluated. These v:Jlucs are required for calculating hydration number nH of L-glycine. Transfer volumes \(ΔV_\phi^0\) and transfer adiabatic compressibilities \(ΔK^0_{\phi,S}\) at infinite dilution from water to aqueous electrolyte solutions have been calculated. Transfer parameters have been interpreted in terms of solutecosolute interactions on the basis of a cosphere overlap model.
