Resumo: | A recent proposal attributes the origin of hydrotropy to the water-mediated aggregation of hydrotrope molecules around the solute. Experimental evidence for this phenomenon is reported for the first time in this work, using 1H-NMR. A new computational technique to quantify apolarity is introduced and is used to show that apolarity of both solute and hydrotrope is the driving force of hydrotropy. This journal is |

The NMR spectrometers are part of the National NMR Network (PTNMR) and are partially supported by Infrastructure Project No. 022161 (co-financed by FEDER through COMPETE 2020, POCI and PORL and FCT through PIDDAC). Financial support from Ministerio de Ciencia, Innovacio ´n (project RTI2018-093431-B-I00) and the Gobierno de Arago´n (Group E37_17R) co-funded by FEDER 2014-2020 ‘‘Construyendo Europa desde Aragón’’ is acknowledged.
