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
Ionic compounds are electrically neutral, so there must be a balance of cations and anions in a compound. When combining, positive ions collect enough negative ions to offset their charge. In any compound, the number of atoms of a ion depends on the ion it is bonding with.
