MCQ
If an iron rod is dipped in $CuS{O_4}$ solution
- ABlue colour of the solution turns green
- ✓Brown layer is deposited on iron rod
- CNo change occurs in the colour of the solution
- DBlue colour of the solution vanishes
✓
Answer
Correct option: B.
Brown layer is deposited on iron rod
b
(b)Brown layer is deposited on iron rod because $Cu$ has greater than reduction potential than that of $F{e^{2 + }}$.
(b)Brown layer is deposited on iron rod because $Cu$ has greater than reduction potential than that of $F{e^{2 + }}$.
