NEET · Chemistry · STD 12 - 2. Electrochemistry
Zinc can be coated on iron to produce galvanized iron but the reverse is not possible. It is because
- A zinc is lighter than iron
- B zinc has lower melting point than iron
- C zinc has lower negative electrode potential than iron
- D zinc has higher negative electrode potential than iron.
Answer & Solution
Correct Answer
(D) zinc has higher negative electrode potential than iron.
Step-by-step Solution
Detailed explanation
\(\mathrm{E}_{\mathrm{Zn}^{+2} / \mathrm{Zn}}^{0}=-0.76 \mathrm{V}\) \(\mathrm{E}_{\mathrm{Fe}^{+2} / \mathrm{Fe}}^{0}=-0.76 \mathrm{V}\)
