Solution

Double displacement reaction:

  • In a molecule, a displacement reaction occurs when one or more atoms are displaced by another atom.
  • A single displacement reaction, also known as a single replacement reaction, is a type of oxidation-reduction chemical process in which an ion or element moves out of a molecule and is replaced by another.
  • When a portion of two ionic compounds is transferred, it creates two new components, which is known as a double displacement reaction.

Real-life Example:

  • The ions precipitate and exchange ions in double displacement processes, which occur most commonly in aqueous solutions.
  • BaCl2(aq)+Na2SO4(aq)BaSO4(s)+2NaCl(aq)BariumSodiumBariumSodiumChlorideSulfateSulphateChloride
  • Make a volcano at home by combining vinegar and baking soda.
  • To transform chemical energy into electrical energy, batteries use electrochemical or redox reactions.
