Question

A reaction cycle for an element is a series of reactions be-ginning and ending with that element. In the following copperreaction cycle, copper has either a 0 or a 2 oxidation state.Write balanced molecular and net ionic equations for each step in the cycle.(1) Copper metal reacts with aqueous bromine to produce agreen-blue solution.(2) Adding aqueous sodium hydroxide forms a blue precipitate.(3) The precipitate is heated and turns black (water is released).(4) The black solid dissolves in nitric acid to give a blue solution.(5) Adding aqueous sodium phosphate forms a green precipitate.(6) The precipitate forms a blue solution in sulfuric acid.(7) Copper metal is recovered from the blue solution when zincmetal is added
