Definizione

cúprico
cúprico, -a (del lat. "cuprum", cobre) adj. Quím. Aplicado a ciertos compuestos de cobre en que éste actúa como bivalente, los cuales tienen doble proporción de oxígeno que los compuestos del mismo nombre denominados "cuprosos".

Wikipedia

Óxido de cobre(II)

El óxido de cobre(II), también llamado antiguamente óxido cúprico ( CuO {\displaystyle {\ce {CuO}}} ), es el óxido de cobre con mayor número de oxidación. Como mineral se conoce como tenorita.

2 Cu + O 2 = 2 CuO {\displaystyle {\ce {2Cu + O2 = 2CuO}}}

Aquí, se forma junto con algo de óxido de cobre(I) como un producto lateral, por lo que es mejor prepararlo por calentamiento de nitrato de cobre(II), hidróxido de cobre(II) o carbonato de cobre(II):

2 Cu ( NO 3 ) 2 = 2 CuO + 4 NO 2 + O 2 {\displaystyle {\ce {2 Cu(NO3)2 = 2 CuO + 4 NO2+ O2}}}
Cu ( OH ) 2 ( s ) = CuO ( s ) + H 2 O ( l ) {\displaystyle {\ce {Cu(OH)2 (s) = CuO (s) + H2O (l)}}}
CuCO 3 = CuO + CO 2 {\displaystyle {\ce {CuCO3 = CuO + CO2}}}

El óxido de cobre(II) es un óxido básico, así se disuelve en ácidos minerales tales como el ácido clorhídrico, el ácido sulfúrico o el ácido nítrico para dar las correspondientes sales de cobre(II):

CuO + 2 HNO 3 = Cu ( NO 3 ) 2 + H 2 O {\displaystyle {\ce {CuO + 2 HNO3 = Cu(NO3)2 + H2O}}}
CuO + 2 HCl = CuCl 2 + H 2 O {\displaystyle {\ce {CuO + 2 HCl =CuCl2 + H2O}}}
CuO + H 2 SO 4 = CuSO 4 + H 2 O {\displaystyle {\ce {CuO + H2SO4 = CuSO4 + H2O}}}

Reacciona con álcali concentrado para formar las correspondientes sales cuprato.

3 XOH + CuO + H 2 O = X 3 [ Cu ( OH ) 6 ] {\displaystyle {\ce {3 XOH + CuO + H2O = X3[Cu(OH)6]}}}

Puede reducirse a cobre metálico usando hidrógeno o monóxido de carbono:

CuO + H 2 = Cu + H 2 O {\displaystyle {\ce {CuO + H2 = Cu + H2O}}}
CuO + CO = Cu + CO 2 {\displaystyle {\ce {CuO + CO = Cu + CO2}}}

Un método de laboratorio para preparar óxido de cobre(II) puede ser electrolizar agua conteniendo bicarbonato de sodio a un voltaje moderado con un ánodo de cobre, recoja la mezcla de hidróxido de cobre, carbonato básico de cobre, y carbonato de cobre producida, y caliéntelo.[3]
