Study of excess acoustic parameters of citric acid in ionic solutions

摘要

The density, viscosity and speed of sound have been measured for the systems (1M NaCl +citric acid) and (1M MgCl2 +citric acid) at different temperatures 298.15, 303.15and 308.15K. The excess acoustic parameters such as excess ultrasonic velocity, excess adiabatic compressibility, excess acoustic impedance, excess intermolecular free length and excess relative association have been calculated for the solutions. The results are interpreted in terms of molecular interactions
