Abstract

Results of cryoscopic, calorimetric, and conductometric investigations of betaine and betaine hydrochloride in aqueous solution are presented and used in subsequent thermodynamic calculations. For the ionization of aqueous [(CH₃)₃N+CH₂COOH] we find ΔG° = 2.50 kcal mole^-1, ΔH° = -0.08 kcal mole^-1, ΔS° = -8.7 cal deg^-1 mole, and ΔC_P° = -7 cal deg^-1 mole^-1. A new freezing point apparatus utilizing thermistors is described.
