Versuchsvorschrift

adding to said solution of chromium(VI) source in aqueous propionic acid, a nitrite source selected from alkali metal and ammonium nitrites, employing sufficient nitrite source to effectively reduce said chromium(VI) source to chromium(III) and allowing sufficient time at sufficient temperature to produce a clear green solution of stabilized chromium(III) propionate; and
