<h3>What are decomposition reactions?</h3>
- 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.
