How do we get “Copper Hydroxide”?
Answers
Answer:
Laboratory synthesis. Copper(II) hydroxide can be produced by adding a sodium hydroxide to a dilute solution of copper(II) sulfate (CuSO4·5H2O). The precipitate produced in this manner, however, often contains water and an appreciable amount of sodium hydroxide impurity.
Answer:
Explanation:
Copper(II) hydroxide can be produced by adding a sodium hydroxide to a dilute solution of copper(II) sulfate (CuSO4·5H2O). The precipitate produced in this manner, however, often contains water and an appreciable amount of sodium hydroxide impurity. A purer product can be attained if ammonium chloride is added to the solution beforehand. Alternatively, copper hydroxide is readily made by electrolysis of water (containing a little electrolyte such as sodium sulfate, or magnesium sulfate) with a copper anode.
