If there is any problem with the scheduling of exams please let me know in advance. Interactions of water with different types of solutes. In water both cations and anions are solvated. Each ion is surrounded by water molecules. The negative oxygen of water faces the cations and the positive end of the water molecule faces anions.
Water has a high dielectric constant.
You can see that as the magnitude of the dielectric constant increases the force exerted by one charge on another decreases. Another way to say this is that the interaction between two charges is attenuated in a medium of high dielectric- or water prevents the charges from getting together. An example is methanol. The hydroxyl group of methanol can serve either as a donor or acceptor in a hydrogen bonding interaction with water. Water forms clathrate structures around nonpolar solutes.
