Q.4. What are the two chemical properties of copper?Ans: The two chemical properties of copper are: (i) Copper reacts with oxygen in the air to form copper (II) oxide. (ii) Copper gets tarnished to blue-green colour forming copper hydroxide and copper carbonate....
The period of unsightliness can now be eliminated by subjecting the copper to electrolytic corrosion under controlled conditions; after 15 minutes an insoluble patina of good green colour is produced, and this, after exposure to the air, is found to have approximately the constitution of bro...
