Element A has replaced Y (in the compound XY) to form a new compound XA and the free element Y. This is an oxidation-reduction reaction wherein element A is reduced from the elemental form into an anion and element Y is oxidized from an anion into the elemental form.

Typically, you will be given the left-hand (reactant side) and asked to provide the products to the reaction. You need to be able to recognize single replacement reactions AND be able to break a formula apart into proper cations and anions as well as write correct formulas.

Single Displacement Reaction Definition: A single displacement reaction is a chemical reaction where one reactant is exchanged for one ion of a second reactant. Single displacement reactions take the form. A + BC → B + AC. Examples: The reaction.

Single displacement reaction. From Wikipedia, the free encyclopedia. A single-displacement reaction, also named single-replacement reaction, is a type of oxidation-reduction chemical reaction when an element or ion moves out of one compound and into another-that is, one element is replaced by another in a compound. This is represented by the general reaction scheme:
