Which of the following statements is true with respect to the reaction of a metal тАШAтАЩ with metal тАШBтАЩ of its solution, in which metal тАШAтАЩ displaces metal тАШBтАЩ?
тАШAтАЩ is more reactive than тАШBтАЩ.
тАШBтАЩ is more reactive than тАШAтАЩ.
Both тАШAтАЩ and тАШBтАЩ have the same reactivity.
The reaction cannot take place at all.
тАШAтАЩ is more reactive than тАШBтАЩ.
A metal 'A' can displace metal 'B' from its salt solution only if 'A' is higher in the reactivity series than 'B'. This is a fundamental characteristic of single displacement reactions governed by the electrode potential of the metals.
A metal 'A' can displace metal 'B' from its salt solution only if 'A' is higher in the reactivity series than 'B'. This is a fundamental characteristic of single displacement reactions governed by the electrode potential of the metals.
Think of this like a strong captain (more reactive metal) taking the place of a weaker player (less reactive metal) on a sports team; the stronger one naturally displaces the weaker one from their position.

Ecell0тАЛ=Ecathode0тАЛтИТEanode0тАЛ тАФ Represents the standard cell potential which must be positive for a spontaneous displacement reaction.
A+B(SO4тАЛ)тЖТA(SO4тАЛ)+B тАФ A general representation of a single displacement reaction.
The reaction follows the principle that a more reactive metal has a greater tendency to lose electrons and form positive ions. During the reaction, the more reactive metal atoms undergo oxidation, transferring electrons to the ions of the less reactive metal, which in turn undergo reduction. The reaction is represented as A+Bn+тЖТAn++B.
Reactivity series is based on the tendency of metals to lose electrons.
A metal higher in the reactivity series can reduce the ions of a metal lower in the series.
These reactions are redox reactions involving electron transfer.
Used in metallurgical processes like the extraction of metals.
Essential for electroplating and battery chemistry.
Highly reactive metals can react vigorously with water, posing safety risks.
Cannot be used to extract metals higher in the reactivity series using less reactive metals.
Thermite process for welding railway tracks.
Extraction of metals from ores.
Standard Electrode Potential (E0) values are measured in Volts (V).
Option B is wrong because a less reactive metal lacks the energy to reduce the ions of a more reactive metal. Option C would result in no net chemical change. Option D is incorrect because spontaneous displacement is common among metals with different electrochemical potentials.
A is correct тАФ A metal 'A' displaces metal 'B' from its solution only if 'A' has a higher tendency to oxidize than 'B', placing it above 'B' in the reactivity series.
Always memorize the metal reactivity series as it is a high-yield topic for both Chemistry and Physics (electrochemistry) sections in Indian competitive exams.
