Abstract: This research has recorded the linewidth of 35Cl of 0.5 mol/L Ca(ClO4)2 solution in ten solvents and the variation of linewidth with concentration of salt in six solvents.The relation between ionic association and the properties of solvent and ion was explored.The linewidth of 35Cl in acetoni-trile or ethanol as bulk solvent at fixed concentration of Ca(ClO4)2 was measured as a function of [B]/[Ca2+], where Brepresents H2Oor DMF.The trend of the plot and the reason for that were explained.The solvation numbers of Ca2+ by solvents were withdrawn from plots.The type of ion pairing of Ca2+ and ClO4- was assumed based on the conductance data.
Key words: Relaxation rate, Ionic association, Ionic solvation
