Question

. Na, Ag, Zn, Cu are the elements in the reactivity series. Which of the given elements can displace iron from its salt solution?

Answer 1

NA and ZN

Explanation:

na and zn are more reactive then the iron therefore it will displace the iron from its salt solution

Answer 2

Answer:

Na,Zn

Explanation:

According to the reactivity series, the E⁰oxidation or we can say the tendency to oxidise in a solution is more for sodium and zinc as compared to iron. Therefore they can displace iron from its solution.

Whereas for Ag and Cu the E⁰ oxidation is less than iron. (they have more tendency to reduce as compared to iron). hence they remain in reduced form in a salt solution of iron. so iron is not displaced by them
