Question

Which one of the following four metals would be displaced from the solution of its salts by other three metals? (a) Mg (b) Fe (c) Zn (d) Cu

Answer 1

Answer:

(b) Fe

Explanation:

Silver (Ag) metal would be displaced from the solution of its salts by other three metals because Ag is less reactive than Mg,Zn and Cu.

Answer 2

Of the following four metals (d) Cu would be displaced from the solution of its salts by other three metals

• In order to determine the reactivity of metals we follow the reactivity series.
• In the reactivity series metals on basis of their reactivity are arranged in descending order from top to bottom.
• The metals on top are most reactive ones and strong reducing agents too while bottom ones are least reactive.
• Among the following given options Copper lies on the bottom category. It is because of this reason it would be displaced from the solution of its salts by other three metals as it's least reactive of all.
