<h2><u>Displacement reaction:</u></h2>
  • A reaction in which an element displaces or replaces another element of a compound is called a displacement reaction.
<h3><u>Types:</u></h3>

There are 2 types:

<h3><u>1. Single displacement reaction:</u></h3>
  • If one element displaces 1 other element of a compound, it is called single displacement reaction.
  • <u>Example</u>:  CuSO_4 +Fe \longrightarrow \ FeSO_4 + Cu
  • Here, 1 element (Fe) displaces 1 other element (Cu) of a compound.
<h3><u>2. Double displacement reaction:</u></h3>
  • If two elements in two compounds displace one another, it is called double displacement reaction.
  • <u>Example:</u> CuSO_4+NaOH \longrightarrow Cu(OH)_2 + Na_2SO_4
  • Here, Copper and sodium both displace each other.
