SECTION 10: Stability and reactivity
10.1
Reactivity
100 mg/cu m (as Cu) Copper dusts and mists
Mixtures with acetylenic compounds, ethylene oxide and azides are shock-sensitive. Reacts with strong oxidants such as chlorates, bromates and iodates strong oxidants such as chlorates, bromates and iodates. This generates explosion hazard.
10.2
Chemical stability
Becomes dull when exposed to air. in moist air gradually becomes coated with green basic carbonate.
10.3
Possibility of hazardous reactions
COPPER combines violently with chlorine trifluoride in the presence of carbon [Mellor 2, Supp. 1, 1956]. Is oxidized by sodium peroxide with incandescence [Mellor 2:490-93, 1946-1947]. Forms an unstable acetylide when acetylene is passed over samples that have been heated enough to form an oxide coating. Reacts more rapidly in powdered or granular form. Subject to explosive reaction then mixed in finely divided form with finely divided bromates chlorates and iodates of barium, calcium, magnesium, potassium, sodium, or zinc; these reactions are initiated by heat, percussion, and occasionally light friction [Mellor 2:310, 1946-1947]. A solution of sodium azide in copper pipe with lead joints formed copper azide and lead azide, both of these compounds can detonate [Klotz, 1973].

Toxicity
- Toxicity to fish: LC50 – Pimephales promelas – 193 µg/L – 96 h.

Copper is a chemical element with the symbol Cu (from Latin: cuprum) and atomic number 29.
It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color.
Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement.
