Question

what is the double displacement reaction ? with examples​

Answer 1

Answer:

what is the double displacement reaction ?

AnsweR:

A double displacement reaction is a type of chemical reaction in which the reactant ions exchange places to form new products.

Example:

AB + CD → AD + CB

Reaction:

calcium chloride (CaCl2) mixes with sodium bicarbonate ( NaHCO3 sodium bicarbonate Sodium bicarbonate reduces stomach acid. ✔️

Hope it will be helpful :)

Answer 2

Answer :

Double displacement reactions generally take place in aqueous solutions in which the ions precipitate and there is an exchange of ions. For example, on mixing a solution of barium chloride with sodium sulphate, a white precipitate of barium sulphate is immediately formed. These reactions are ionic in nature.

Example : CuCl₂ + 2 AgNO₃ → Cu(NO₃)₂ + 2 AgCl
