# Why are nitrates always soluble?

Because the nitrate is not charge dense, the species in solution is less polarizing (as the nitrate ion, $N {O}_{3}^{-}$), and causes less solvent order upon dissolution. For this reason, many nitrate salts have solubility in non-aqueous solvents. Inorganic chemists generally do not exploit this solubility, because the nitrate ion is still a potent oxidant, although in the aqueous phase this reactivity is somewhat masked.
