singledisplacement
Single-displacement, or single-replacement, is a type of chemical reaction in which an element reacts with a compound and displaces another element from that compound to form a new element and a new compound. The general form is A + BC → B + AC, where A replaces B.
It is a redox process: A is typically more reactive than B, so A is oxidized and
Reactions occur only when the entering element A is more reactive than the element it replaces. Predictability
Common examples include zinc displacing copper from copper(II) sulfate: Zn + CuSO4 → ZnSO4 + Cu. Iron can displace
Single-displacement reactions have applications in metallurgy, electrochemistry, and qualitative analysis, where reactivity trends guide metal extraction
