Metals will displace another metal from the solution of its salt if
Correct answer: A. It lies above in electrochemical series
- A. It lies above in electrochemical series
- B. It lies below in the electrochemical series
- C. Cannot replace
- D. None
Explanation
The electrochemical series is a list of metals arranged in order of their standard electrode potentials. When a metal is placed above another metal in the electrochemical series, it means that the metal higher in the series is more reactive or has a higher tendency to lose electrons.According to the reactivity series, a metal higher in the series can displace a metal lower in the series from its salt solution. This is based on the principle of the metal being a more effective reducing agent and having a greater tendency to lose electrons.The general reaction for such displacement reactions is represented as follows:

About Transition Elements
Transition elements are identified by their partially filled d subshells in atoms or common ions. The topic covers the electronic structure of d-block elements, including the filling order of 4s and 3d orbitals, variable oxidation states and the distinction between transition elements and elements with completely filled d subshells.
