Question

what are the types of double displacement reaction

Answer 1

Double displacement reaction
The reaction in which reactive molecule exchange with each other
They are divided into two parts ::--
1.Nutrilisation
->In this reaction acid react with base to form salt and water.
2.Precipitation
->It is a kind of double displacement reaction in which two products are formed out in which one is insoluble in water.

Answer 2

Hey friend ☺

Here is your answer

There are mainly two types of double displacement reactions :

•NEUTRALIZATION REACTION :

The reaction between an acid and base to form salt and water is called neutralization reaction.
EXAMPLE :
NaOH+HCl=>NaCl +H2O

•PRECIPITATION REACTION:

The reaction which is characterized by the formation of precipitate is called precipitation reaction.
EXAMPLE:
2KI+Pb(NO3)2=>PbI2+2KNO3
