konstantin123 [22]

A precipitate forms from a double displacement reaction or metathesis.

Explanation:

If given two clear solutions and upon reacting a cloudy/insoluble substance forms with the rest of the liquid being clear, a double displacement reaction has been carried out. The insoluble cloudy substance is called precipitate.

  1. the driving force for the bulk of double displacement reactions is the formation of precipitates.
  2. from careful observations, a solubility chart has been developed. If the compounds reacting are known, using the chart, a chemist can predict whether a precipitate will form or not.
