Metals X and Y can be recovered from the anode mud left behind after the electrolytic refining of copper metal. The coins made of metal X look new even after several years of use but the coins made of metal Y lose their shine gradually and get blackened soon. When metal X is alloyed with a small amount of metal Y, it becomes hard and hence suitable for making ornaments. What are metals X and Y ? Also state the colour of metal X.

Answer» METAL X is PURE Goldmetal Y is CopperExplanation:copper reacts with ATMOSPHERIC OXYGEN so it's metallic lustre losesgold doesn't react with oxygen so it can be shine even after yearsthe color of the Gold is Metallic Golda COUSIN color of yellow and brownthe color of copper is brown
