Thread: enthalpy of solvation of sodium in h20

Given the question, in which solvent should Na+ have the most negative enthalpy of solvation?

out of CCl4, H2O,C6H6 CS2 and CH3OCH3

i chose water.

my reason - Because Na+ is an ion, water being so bloody polar, it would be favourable to dissolve, more so in this than in any of the other's

and a negative enthalpy = favourable reaction?

IT IS HOMEWORK, i know. but i just need a simple right or wrong,
