Analytical Methods
Nickel(II) oxide (CAS NO.1313-99-1),its occupational chemical analysis use NIOSH: Nitric Oxide s321.
Specification
The Nickel(II) oxide, with the cas registry number 1313-99-1, is a kind of green to dark green powder. This is soluble in acid and ammonia water while insoluble in water and liquid ammonia and it is stable chemically but incompatible with strong acids. When heated to 400 °C, it will produce nickelic trioxide after absorbing oxygen, and then restore to nickel monoxide when heated to 600 °C.
