Prediction of Refractive Indices of Binary Mixtures of Ionic Liquids and Water

<div>Experimental refractive index values (circular symbols) as a function of ionic liquid (IL) mole fraction (<i>x</i><sub>IL</sub>) for the four selected IL + H<sub>2</sub>O systems belong to imidazolium (M8), pyrrolidinium (M9), pyridinium (M15), and ammonium (M28) families along with the predicted values using Gladstone–Dale (green line) and Newton (red line) approach at 298.15 K. The best results (lowest average percentage deviations) were obtained for these systems in respective families.</div>
