Question

What is double displacement reaction ?? ​

Answer 1

Explanation:

A double displacement reaction is a type of chemical reaction where two compounds react, and positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products. For example, Na2S+2HCl→2NaCl+H2S.

Answer 2

Those reactions in which two compounds react by an exchange of ions to form two new compounds are called double displacement reactions.
