Chemical Properties
Green, deliquescent crystals.Soluble in water, ammonium
hydroxide, and alcohol.
Chemical Properties
Nickel nitrate is a green powder.
General Description
NICKEL NITRATE(13138-45-9) is a green crystalline solid. NICKEL NITRATE(13138-45-9) is soluble in water. NICKEL NITRATE(13138-45-9) is noncombustible, but NICKEL NITRATE(13138-45-9) will accelerate the burning of combustible materials. If large quantities are involved in a fire or the combustible material is finely divided, an explosion may result. Prolonged exposure to fire or heat may result in an explosion. Toxic oxides of nitrogen are produced in fires involving this material. NICKEL NITRATE(13138-45-9) is used in nickel plating and to make nickel catalysts for use in chemical manufacture.
Reactivity Profile
Green, crystalline material, toxic and carcinogenic. A powerful oxidizer, NICKEL NITRATE may cause a violent reaction with reducing materials (e.g., magnesium or aluminum powder, tin(II) chloride). Dangerous fire hazard, acts as oxygen carrier. When heated to decomposition NICKEL NITRATE emits highly toxic fumes of oxides of nitrogen [Lewis, 3rd ed., 1993, p. 915]. Complexes with tetrammine and tetrahydrazine are explosive [Bretherick, 5th ed., 1995, p. 1685].
Air & Water Reactions
Soluble in water.
Hazard
Dangerous fire risk, strong oxidizing agent.
Health Hazard
Inhalation of dust causes irritation of nose and throat. Ingestion causes vomiting. Dust irritates eyes and may cause dermatitis in contact with skin.
Potential Exposure
Nickel nitrate is used in electroplating,
in nickel catalyst production for making other chemicals
and the manufacture of brown ceramic colors.
First aid
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions, including
resuscitation mask) if breathing has stopped and CPR if
heart action has stopped. Transfer promptly to a medical
facility. When this chemical has been swallowed, get medical
attention. Give large quantities of water and induce
vomiting. Do not make an unconscious person vomit.
Shipping
UN2725 Nickel Nitrate, Hazard Class: 5.1;
Labels: 5.1-Oxidizer.
Incompatibilities
A strong oxidizer. Incompatible with
strong acids; sulfur, combustibles, organics, and other easily
oxidizable materials. Noncombustible, but it will accelerate
the burning of combustible materials. If large
quantities are involved in a fire or the combustible material
is finely divided, an explosion may result. Prolonged exposure
to fire or heat may result in an explosion.
Waste Disposal
Consult with environmental
regulatory agencies for guidance on acceptable disposal
practices. Generators of waste containing this contaminant
(≥100 kg/mo) must conform with EPA regulations
governing storage, transportation, treatment, and waste
disposal.
