Double displacement reaction is a chemical reaction in which 2 ionic compound change switch their components to make new compound, you can think about is as swapping of anions or cations between the two compounds:

Let us take for example:

$B a C l_{2} + N a_{2} S O_{4} \to B a S O_{4} + 2 N a C l$ $BaCl_2 + Na_2SO_4 rarr BaSO_4 + 2NaCl$

$B a^{2 +} 2 C l^{-} + 2 N a^{+} S O_{4}^{2 -}$ $Ba^(2+)2Cl^(-) +2Na^+SO_4^(2-)$

by switching the anions or cations we get:
$B a^{2 +} S O_{4}^{2 -} + 2 N a^{+} 2 C l^{-}$ $Ba^(2+)SO_4^(2-) +2Na^+2Cl^(-)$

$B a^{2 +} 2 C l^{-} + 2 N a^{+} S O_{4}^{2 -} \to B a^{2 +} S O_{4}^{2 -} + 2 N a^{+} 2 C l^{-}$ $Ba^(2+)2Cl^(-) +2Na^+SO_4^(2-) rarr Ba^(2+)SO_4^(2-) +2Na^+2Cl^(-)$
$\to$ $rarr$
$B a C l_{2} + N a_{2} S O_{4} \to B a S O_{4} + 2 N a C l$ $BaCl_2 + Na_2SO_4 rarr BaSO_4 + 2NaCl$
