Behavior of Dissociated Salts in Aqueous Solution: Insights From T₂ Relaxation Time and Signal Intensity Using a LF-NMR.

ABSTRACT: This study explores the influence of NaCl, KCl, CaCl₂, and MgCl₂, salts commonly used in the food industry, on aqueous solutions using transverse (T₂) relaxometry in low- field nuclear magnetic resonance (LF-NMR) at a salt-to-water ratio ranging from 0 to 0.1079 mol/mol. The results demonstrate that T₂ relaxation times are significantly affected by the chemical nature and concentration of the ions, with divalent salts exhibiting distinct behavior compared to monovalent salts. Notably, the kosmotropic (structure-making) and chaotropic (structure-breaking) properties of the salts were found to influence relaxation times. Mg²⁺ exhibited the most pronounced effect (low relaxation time) due to its high charge density and strong hydration ab
