Sodium Cobaltinitrite is a yellow powder. It is hygroscopic. It is easy to dissolve in water and slightly soluble in alcohol. An identification reagent used as a potassium ion. Sodium Cobaltinitrite is a deep orange powder, soluble in water.Cobalt sodium nitrite can be destroyed by strong acid and strong alkali. Its aqueous solution is unstable and can be decomposed slowly at room temperature. [Co (NO2) 6]3- ions (cobalt nitrite (III) ions) interact with acetylacetone and only four nitro can be replaced. The reaction product has a trans structure. Due to the inverse position effect, a coordination nitro group is easily replaced by ammonium (amine).

Sodium Cobaltinitrite Attention:
Remove contaminated clothing and rinse with plenty of fresh water.
Lift eyelids and rinse with flowing or normal saline. Go to a doctor.
Quickly out of the scene to the fresh air. Keep the respiratory tract unobstructed. If breathing is difficult, oxygen is given. If breathing is stopped, artificial respiration is carried out immediately. Go to a doctor.
Drink plenty of warm water and urge vomiting. Go to a doctor
Sodium cobaltinitrite should be placed in low temperature, dry and ventilated storeroom. Tight doors and windows to prevent direct sunlight. It can be stored in the same store as nitrate other than ammonium nitrate, but it is isolated from organic matter, combustibles and reducing agents and is isolated from fire sources.
