Write down the reaction equations allowing to carry out the following chain of transformations Cu-Cuo-CuCl2-Cu (OH) 2
| December 3, 2020 | education
Cu – CuO – CuCl2 – Cu (OH) 2
1.2Cu + O2 = 2CuO oxidation (combustion) reaction
2.CuO + 2HCl = CuCl2 + H2 add hydrochloric acid
3.CuCl2 + 2NaOH = Cu (OH) 2 + 2NaCl add sodium hydroxide
