Displacement reactions provide better evidence about the reactivity of metals as they involve direct competition between different metals for a non-metal part of a compound. The metal that displaces another is more reactive. This method is superior because it accounts for the metal’s ability to displace another from a compound, showcasing its overall reactivity. It offers a comparative and standardized approach, unaffected by factors like concentration or physical state, providing a clearer understanding of the metal’s relative reactivity. Displacement reactions, such as those in salt solutions, serve as a more robust and versatile indicator of metal reactivity compared to individual reactions with oxygen, water, or acids.
