Answer 1

Answer:

A double displacement reaction, also known as a double replacement reaction or metathesis, is a type of chemical reaction where two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products.

Answer 2

Answer:

A double displacement reaction is defined as exchange of atoms(or ions) between elements or compounds to form new substances. This types of reactions are also known as metathesis.

For example,

Reaction between Barium chloride and Sodium sulphate forms Barium sulphate and Sodium chloride.

BaCl2(aq)+Na2SO4(aq)====>

2NaCl(aq)+BaSO4(aq)

Here BaSO4 is a white precipitate

•These reactions are instanteous

•In these reactions,chances of formation of precipitates are more.
