Fundamental findings about nitric acid dissociation will feed into atmospheric research on ozone depletion

Up to 70% of nitric acid remains undissociated when adsorbed on nanoparticles of ice, new research shows. This is in stark contrast to how nitric acid behaves in water and on bulk amorphous ice, where it dissociates fully.
