\(2Cu+O_2\underrightarrow{^{^{t^o}}}2CuO\)
\(CuO+2HCl\rightarrow CuCl_2+H_2O\)
\(CuCl_2+2NaOH\rightarrow Cu\left(OH\right)_2+2NaCl\)
\(Cu\left(OH\right)_2+H_2SO_4\rightarrow CuSO_4+2H_2O\)
\(CuSO_4+Ba\left(NO_3\right)_2\rightarrow Cu\left(NO_3\right)_2+BaSO_4\)
Cu --(Oxi hóa)--> CuO --(Phản ứng với HCl)--> CuCl2 --(Phản ứng với NaOH)--> Cu(OH)2 --(Phản ứng với H2SO4)--> CuSO4 --(Phản ứng với HNO3)--> Cu(NO3)2
____________________HT_________________________
2Cu + O2 ---> 2CuO
CuO + HCl ---> CuCl2 + H2O
CuCl2 + Ba(OH)2 ---> Cu(OH)2 + BaCl2
Cu(OH)2 ---to--> CuO + H2O
CuO + SO3 ---> CuSO4
CuSO4 + Pb(NO3)2 --->Cu(NO3)2 + PbSO4
