In some cases, the forces that hold the salt together are too strong for the water molecules to pull apart. These are called insoluble salts. You can tell if you have an insoluble salt by the formation of a precipitate when combining solutions of soluble salts, or a gas is evolved (observed as gas bubbles, or a foam). For the following reactions, the indicated solutions…
