What are the products of a double displacement reaction?
One of the products must be a solid precipitate, an insoluble gas, or water.
A double displacement (double replacement) reaction occurs when two aqueous ionic solutions react to produce a solid precipitate, an insoluble gas, or water. If none of these are produced, then a double displacement did not take place.
The general equation for a double displacement reaction is
