Question

Give examples of Double displacement reactions.

Answer 1

Double displacement reaction:

1. A kind of reaction called a double displacement reaction involves the exchange of ions between two reactants to create two new molecules.
2. Ionic chemicals that are dissolved in water undergo several double displacement reactions with one another.
3. The general equation describes a twofold replacement reaction.

Example:

${\mathrm{AgNO}}_3\left(\mathrm{s}\right)+\mathrm{HCl}\left(\mathrm{l}\right)\rightleftharpoons \mathrm{AgCl}\left(\mathrm{s}\right)+{\mathrm{HNO}}_3\left(\mathrm{l}\right)$
