A copper coin was electroplated with \(\mathrm{Zn}\) and then heated at high temperature until there is a change in colour. What will be the resulting colour?
- A white
- B black
- C silver
- D golden
Answer & Solution
Correct Answer
(D) golden
Step-by-step Solution
Detailed explanation
A copper coin was electroplated with zinc (Zn) and then heated at high temperature until there is a change in colour. The resulting colour will be golden. The golden colour is due to the zinc migrating through the copper to form the alpha-form of brass alloy (percentage of…
