Abstract
Volume changes in the course of neutralization of solutions of nitrilotris(methanephosphonic), hydrochloric, and nitric acids with aqueous ammonia solution were measured dilatometrically at 298 K. The changes in the molar volumes were calculated for various stages of the neutralization. The data were com- pared to the results of titration of nitrilotris(methanephosphonic) acid with strong hydroxyl-containing bases. The specific features of reactions of ammonia with acids and the state of nitrilotris(methanephosphonic) acid in various stages of its dissociation were taken into account in data interpretation.
