\(CuO\underrightarrow{1}CuSO_4\underrightarrow{2}Cu\left(OH\right)_2\underrightarrow{3}CuCl_2\underrightarrow{4}Cu\left(OH\right)_2\)
(1) \(CuO+H_2SO_4\rightarrow CuSO_4+H_2O\)
(2) \(CuSO_4+2NaOH\rightarrow Cu\left(OH\right)_2+Na_2SO_4\)
(3) \(Cu\left(OH\right)_2+2HCl\rightarrow CuCl_2+2H_2O\)
(4) \(CuCl_2+2KOH\rightarrow Cu\left(OH\right)_2+2KCl\)
Chúc bạn học tốt
CuO + H2SO4 --> CuSO4 + H2O
CuSO4+2NaOH->Cu(OH)2+Na2SO4
Cu(OH)2+2HCl->CuCl2+2H2O
CuCl2+2NaOH->2NaCl+Cu(OH)2
