A double displacement reaction, also known as a double replacement reaction, is a type of chemical reaction that occurs when two ionic compounds are mixed and switch ions to form two new compounds.

Steps to Balancing Double Displacement Reactions:

1. 1. Write the balanced chemical equation.

   2. Identify the cations and anions in each compound.

   3. Swap the anions between the compounds.

   4. Determine the products of the reaction.

Tips to remember:

• 1. Double displacement reactions are also known as metathesis reactions.

  2. Double displacement reactions often occur in aqueous solutions.

  3. The reaction can be identified by the formation of a precipitate, gas, or water.
