Write the equation of reactions with which you can carry out a chain of transformations of substances: copper – copper chloride (2) – copper hydroxide (2) – copper oxide (2) – Copper sulfate (2) – copper
The chain of transformations.
1. Reaction of copper with chlorine.
Cu + Cl2 = CuCl2.
2. The reaction of the exchange of copper chloride and sodium hydroxide.
CuCl2 + 2NaOH = Cu (OH) 2 + 2NaCl.
3. The reaction of decomposition of copper hydroxide.
Cu (OH) 2 = CuO + H2O.
4. With dilute acid, copper oxide forms a salt.
CuO + H2SO4 = H2O + CuSO4.
5. Reaction of substitution of copper for aluminum.
3CuSO4 + 2Al = Al2 (SO4) 3 + 3Cu.
