What are metathesis reactions?
A metathesis reaction is a reaction in which cations and anions change partners.
A metathesis reaction is a reaction in which cations and anions change partners.
A general equation for a metathesis is ##color(red)”A”color(blue)”X”+color(green)”C”color(purple)”Y”####rarr####color(red)”A”color(purple)”Y”+color(green)”C”color(blue)”X”##, where ##color(red)”A”## and ##color(green)”C”## are cations, and ##color(blue)”X” and color(purple)”Y”## are anions.
There are three possible products of a metathesis reaction.
A. an insoluble (solid) precipitate
B. water (from reaction)
C. an insoluble gas that bubbles out of solution
Metathesis reactions are also called and double displacement reactions.
The following video illustrates a precipitation reaction, an example of a metathesis reaction that forms a precipitate.
