Question
In a redox displacement reaction, if element X loses electrons and element Y gains electrons, then:
The correct answer is
X is oxidised and Y is reduced
Redox Reaction Fundamentals
In a redox reaction, two key processes occur: oxidation and reduction. Understanding these is crucial for analyzing chemical changes.
- Oxidation is defined as the loss of electrons by a species. When an element loses electrons, its oxidation state increases.
- Reduction is defined as the gain of electrons by a species. When an element gains electrons, its oxidation state decreases.
Analyzing Element X and Element Y
The question states that element X loses electrons. According to the definition, the loss of electrons signifies oxidation.
- Therefore, element X is oxidised.
The question also states that element Y gains electrons. The gain of electrons signifies reduction.
- Therefore, element Y is reduced.
Conclusion for Redox Displacement
Combining these findings, in this specific redox displacement reaction, element X is oxidised and element Y is reduced. This directly matches one of the provided options.
The correct statement is: X is oxidised and Y is reduced.
