double decomposition
Definition
- Noun:
- A chemical reaction between two compounds in which parts of each are interchanged to form two new compounds (AB+CD=AD+CB): This is a specific type of chemical reaction, also known as a metathesis reaction, where the positive and negative ions of two ionic compounds exchange partners.
Usage Examples
- Noun:
- The formation of a precipitate in the solution was a clear sign of a double decomposition reaction.
- In the laboratory, we observed a double decomposition when we mixed silver nitrate with sodium chloride, producing silver chloride and sodium nitrate.

- Double decomposition reaction (n): A more formal or explicit term for the same process.
- The experiment demonstrated a classic double decomposition reaction.
- Metathesis (n): A broader chemical term that includes double decomposition reactions.
- Olefin metathesis is an important industrial process, distinct from ionic double decomposition.
Synonyms
- Metathesis reaction: A more general synonym, often used in advanced chemistry.
- Exchange reaction: A descriptive synonym highlighting the exchange of ions.
Related Phrases
