Which of the following is the reason for why water is good at dissolving ionic compounds? Water molecules can form hydrogen bonds with most ions, and since these interactions are stronger than those usually found in the lattices of ionic compounds, dissolution of these lattices tends to be favored O As an ionic compound itself, water should be able to dissolve ionic compounds as "like dissolves like" O Water molecules possess both negatively and positively charged regions, which interact with positive ions (cations) and negative ions (anions) respectively, coating ions and thus hindering their ability to form a lattice O The combination of water and ions usually forms more entropically favored lattices than just those of pure water and pure ionic compounds O Water molecules can covalently bind to each other to form "flickering clusters" which envelop ions in a hydration layer that isolate them from each other, thus making it hard for them to form a lattice and easy for lattices to dissolve
