What is an insoluble solid that forms as the result of a double-displacement reaction called?
It is called a precipitate because it "falls out" of solution, like precipitation such as rain falls out of the sky.
A double displacement (double replacement) reactions takes place when two aqueous ionic solutions react. One of the products must be a precipitate, an insoluble gas, or water.
The general form for a double displacement reaction in which a precipitate forms, also called a precipitation reaction or salt metasthesis, is as follows:
