Understanding ion-solvent interactions is crucial in pharmaceutically important liquid systems, where solubility and stability play pivotal roles in drug formulations. In this study, we investigate ion-solvent interactions using a combination of the speed of sound and apparent molal volume approach. Through experimental measurements and theoretical analysis, we explore the influence of ions on the acoustic and volumetric properties of liquid systems relevant to pharmaceutical formulations. Our findings provide insights into the molecular-level interactions between ions and solvents, shedding light on the underlying mechanisms governing solvation processes in complex pharmaceutical solutions.
