Julius Tafel discovered that hydroxylamine hydrochloride or sulfate salts can be produced by electrolytic reduction of nitric acid with HCl or Sulfuric acid| respectively:
Hydroxylamine can also be produced by the reduction of nitrous acid or potassium nitrite with bisulfite:
: (100 °C, 1 h)
Hydrochloric acid disproportionates nitromethane to hydroxylamine hydrochloride and carbon monoxide via the hydroxamic acid.  
A direct production of hydroxylamine from molecular nitrogen is also possible in water plasma.
