Solution

Double Decomposition Reaction
In such reactions, two kinds of compounds are produced, one is soluble and other one is insoluble.
Lead sulfate $({PbSO}_{4})$ is prepared by double decomposition.
Chemical Reaction
The chemical reaction is as follows:
$Pb {({NO}_{3})}_{2} (aq) + {Na}_{2} {SO}_{4} (aq) \to {PbSO}_{4} ↓ + 2 {NaNO}_{3} (aq)$
