Explanation:

We need to know:

What are decomposition reactions?

  • Decomposition reactions are type of reactions in which a compound is broken down into two or more products.
  • When a soluble substance or a compound is dissolved in water it forms an aqueous solution.
  • When this happens the soluble compound such as ionic compounds ionizes to form ions.
  • This is an example of decomposition reaction, since the ionic compound decomposes it ions making it.
  • For example, sodium sulfide is an ionic compound that ionizes in water to form sodium and sulfide ions.
  • That is;

Na₂S(s) → 2Na⁺(aq) + S²⁻(aq)
