Metathesis Reactions
A reaction such as
NaCl(aq) + AgNO3(aq) = AgCl(s) + NaNO3(aq)
in which the cations and anions exchange partners is called metathesis. In actual fact, the chemistry takes place in several steps. When the chemicals (sodium chloride and silver nitrate) are dissolved, they become hydrated ions:
NaCl(s) + 12 H2O ® [Na(H2O)6]+ + [Cl(H2O)6]-
AgNO3(s) + 12 H2O ® [Ag(H2O)6]+ + [NO3(H2O)6]-
When the silver ions and chloride ions meet in solution, they combine and form a solid, which appears as a white precipitate:Ag+(H2O)6 + + [Cl(H2O)6]- ® AgCl(s) + 12 H2OThe above equation shows the net ionic reaction, whereas the bystander ions Na+and NO3- are not shown. Bystander ions are also called spectator ions. A sound movie is available from the Journal of Chemical Education page on sodium chloride and silver nitrate reactions. This movie plays fine on Polaris computers, but ear phones are required for sound movies.
Metathesis reactions not only take place among ionic compounds, they occur among other compounds such as Sigma Bond Metathesis and Olifin Metathesis. Metathesis reaction is a type of chemical reactions, which include combination, decomposition, and displacement
