Neutralization reaction & a precipitation reaction.

Answer
Neutralization reactionPrecipitation reaction
A reaction between two compounds - base and acid to give two new compounds - salt and water - by interchange of radicals is called a Neutralization reaction.A reaction between two compounds in aqueous solution state to give two new compounds one of which is insoluble (precipitate) is called a Precipitation reaction.
For example:
NaOH + HCl ⟶ NaCl + H2O
For example:
Pb(NO3)2 + 2NaCl ⟶ 2NaNO3 + PbCl2
