CuO+H₂=Cu+H₂O
Cu+2H₂SO₄(конц.)=CuSO₄+2SO₂↑+2H₂O
Cu+4HNO₃=Cu(NO₃)₂+2NO₂↑+2H₂O
2Cu + 4HCl + O₂ = 2CuCI₂ + 2H₂O
CuCI₂+2NaOH=Cu(OH)₂+2NaCI
Cu(OH)₂+H₂SO₄=CuSO₄+2H₂O
2CuSO₄+эл. ток+2H₂O=2Cu+O₂↑+2H₂SO₄
2. CuCI₂→Cu→CuO→Cu(NO₃)₂→Cu(OH)₂→Cu₃(PO₄)₂
CuCI₂+Fe=Cu+FeCI₂
2Cu+O₂=2CuO
CuO+2HNO₃=Cu(NO₃)₂+H₂O
2Cu(NO₃)₂+t°C=2CuO+4NO₂↑+O₂↑
Cu(NO₃)₂+2NaOH=Cu(OH)₂↓+2NaNO₃
3Cu(OH)₂+2H₃PO₄=Cu₃(PO₄)₂+6H₂O
