ionic compound precipitate from a solution of the constituent ions is when the solution is basic or acid. first the ionic compound is allowed to dissociate into ions, when almost all the ions are dissociated a strong acid or base is added to change the ph, in order to precipitate the ions
Best Answer: By definition a precipitate is a substance which is insoluble in the ( usually) liquid medium in which it occurs. In most examples of precipitate formation , a solid settles out to the bottom of the container and is easily seen. But this is not strictly necessary .

This compound is insoluble in water , but it will remain suspended for a long time - the suspension is called milk of magnesia because of its appearance
