cupric compounds are generally green or blue, and are soluble in ammonia, forming deep blue solutions.
The first of these was no doubt finely divided copper metal; the second, third, and fourth were probably all cupric oxide.
The cupric salts are much the more common of the two, since the cuprous salts pass readily into cupric by oxidation.
cupric sulphide, CuS, occurs in nature as the mineral covellite.
The weights of cupric oxid averaged 210 mg., or 72 per cent.
The bulk of the copper is thus transformed into cupric chloride, little cuprous chloride being obtained.
Contrast the action of heat on cupric nitrate and mercuric nitrate.
cupric fluoride, CuF2, is obtained by dissolving cupric oxide in hydrofluoric acid.
Next boil it along with cupric oxide, which precipitates only the uranic and ferric oxides.
It will take some time for any cupric ions actually to reach the electrode and be deposited as metallic copper.
cupric cu·pric (kōō'prĭk, kyōō'-)
Of or containing divalent copper.
Containing copper, especially copper with a valence of 2. Compare cuprous.
