Metathesis reactions are the Reactions in which two compounds react to form two new compounds, with no changes in oxidation number. e.g Reactions in which the ions of two compounds exchange ions. What are the ways in which ions can be removed from solution and thus drive a metathesis reaction? 1.
What is the driving force of a metathesis reaction?
Metathesis reactions are the Reactions in which two compounds react to form two new compounds, with no changes in oxidation number. e.g Reactions in which the ions of two compounds exchange ions. The driving force for metathesis reactions is the removal of ions from solution.

There are three possible products of a metathesis reaction. A. an insoluble (solid) precipitate B. water (from neutralization reaction) C. an insoluble gas that bubbles out of solution
When does metathesis occur between two inorganic salts?
Metathesis reactions can occur between two inorganic salts when one product is insoluble in water, driving the reaction forward, as in the following examples: One of the compounds formed is usually a precipitate, an insoluble gas that bubbles out of the solution or an insoluble solid, or a molecular compound, usually water.
