Single Displacement Reaction
Single Displacement Reaction is a reaction in which one element is displaced by another element of a compound. This reaction is a specific type of oxidation-reduction chemical reaction. In this reaction, a change of colour is observed, however, no precipitate is formed in this reaction. Since this reaction involves the displacement of one element only therefore it is also known as a Single Replacement Reaction.
The general form of a single-displacement reaction is illustrated as:
A + BC → B + AC
Single Displacement Reaction Definition
Single displacement reaction is a type of oxidation-reduction chemical reaction in which an ion or element moves out of a compound, i.e., one element in a compound is replaced by another element.
Single Displacement Reaction Examples
When chlorine is reacted with sodium bromide, sodium chloride and bromine is formed. This reaction is as follows:
Cl2(aq) + 2NaBr(aq) → NaCl + Br2(aq)
In this reaction, Bromine is replaced by chlorine which results in the formation of sodium chloride.
Two more examples of Single Displacement Reaction are:
- Mg (s) + 2HCl (aq) → MgCl2 (aq) + H2 (g)
- 2K (s) + 2H2O (l) → 2KOH (aq) + H2 (g)
Displacement Reaction
Displacement Reaction, also known as single replacement reaction, is a chemical reaction in which one element displaces another element in a compound. In this reaction, the less reactive element is replaced by a more reactive element or metal which results in the formation of a new substance.
In this article, we will discuss displacement reactions, single displacement reactions, and double displacement reactions along with their examples.
