A precipitation reaction is a reaction in which soluble ions in separate solutions are mixed together to form an insoluble compound that settles out of solution as a solid.That insoluble compound is called a precipitate.Solubility Rules for Ionic Compounds.esson 3: Precipitation Reactions.

The finding that extrinsic rewards can undermine intrinsic motivation has been highly controversial since it first appeared (Deci, 1971).
