Question

What are some real-life double displacement reaction examples?

Answer 1

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.
• $$\begin{gathered} {\mathrm{BaCl}}_2\left(\mathrm{aq}\right)+{\mathrm{Na}}_2{\mathrm{SO}}_4\left(\mathrm{aq}\right)\to {\mathrm{BaSO}}_4\left(\mathrm{s}\right)+2\mathrm{NaCl}\left(\mathrm{aq}\right) \\ \mathrm{Barium}\mathrm{Sodium}\mathrm{Barium}\mathrm{Sodium} \\ \mathrm{Chloride}\mathrm{Sulfate}\mathrm{Sulphate}\mathrm{Chloride} \end{gathered}$$
• Make a volcano at home by combining vinegar and baking soda.
• To transform chemical energy into electrical energy, batteries use electrochemical or redox reactions.
