4. Double replacement reactions (Ionic reactions) Ions of 2 Separate compounds change places. Almost always take place in aqueous solution (aq). Both reactants must be soluble (aq) One product is usually soluble and the other may be a solid precipitate or may be gas (g) or may be water (l) General form: AX t BY → AY t BX
