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 ΔCP° = -7 cal deg-1 mole-1. A new freezing point apparatus utilizing thermistors is described.
