Why are many ionic compounds not soluble in water? A. They are non-polar and do not mix well with H2O B. They have metals that are much denser than water C. They have high charge density which makes stronger ionic bonds that water can’t break D. They have weak ionic bonds that cause them to precipitate E. The higher pressure of water causes solids to precipitate
