Which of the following methods is suitable for preventing an iron frying pan from rusting?
- Applying grease
- Applying paint
- Applying a coating of zinc
- All of the above.
The Correct Option is C
Solution and Explanation
Zinc acts as a sacrificial anode and corrodes in place of iron, protecting the iron from rusting. This process is known as galvanization, and it is an effective method to prevent corrosion (rusting) of iron. Applying grease can provide some protection, and applying paint can also be a barrier against moisture, but these methods may not be as durable or effective as the application of a zinc coating.
So, the correct option is (C): Applying a coating of zinc.

- Given below are two statements: One is labelled as Assertion (A) and the other is labelled as Reason (R):
Assertion (A): Type B metal ions form more stable complexes compared to Type A metal ions.
Reasons (R): High electro-negativity (in relative terms) of metal and low electro-negativity of the legand donor atom would be consistent with stability of a complex with Type B metal ion.

- Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R.
Assertion A: Stability of most complexes with the alkaline earth metals is in the order Mg2+ > Ca2+ > Sr2+> Ba2+
Reason R :For type A ions, Electrostatic model approximately explain the stability of metal-ligand complexes that is, stability of these complexes is positively correlated with the ratio of Z2/r for both metal ion and the ligand species.
