Double displacement reaction : A reaction in which two reactants exchange ions to form new compounds.
There are three types of double displacement reactions
1) Precipitation
2) Neutralization (acid-base)
3) Gas formation.
Given equations are examples of acid base reactions.
Equation 1 : HBr + NaOH NaBr +
H2O
Equation 2 : 2 HCl + Mg(OH) 2 MgCl
2 + 2 H2O
