It is also attacked by acetic acid and other organic acids.|COPPER FORMS TWO SERIES OF SALTS, CU(1+) AND CU(2+) BOTH VALENCE TYPES FORM COMPLEX IONS THAT ARE STABLE.|Ductile, excellent conductor of electricity. Complexing agent, coordination numbers 2 and 4. More resistant to atmospheric corrosion than iron, forming green layer of hydrated basic carbonate. Readily attacked by alkalies. Noncombustible, except as powder.|For more Other Experimental Properties (Complete) data for COPPER, ELEMENTAL (6 total), please visit the HSDB record page.

    Air and Water Reactions:

    Solid pieces are very slowly oxidized by air to give a green basic carbonate. Solid pieces become covered by a black oxide when heated in air. Insoluble in water.

    Reactive Group:

    Metals, Less Reactive

    Reactivity Profile:

    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].

    Flammable Limits:

    Noncombustible Solid in bulk form, but powdered form may ignite.

    Heat of Vaporization:
