Solution Chemistry In the first week of class we learned that a homogeneous mixture of two or more  substances is called a solution. If one of the substances is present in much greater  quantities than all the other substances then it is called the  solvent . The other  substances in solution are known as  solutes . For example, when a small amount  of NH 4 Cl is dissolved in a large quantity of water we refer to water as the solvent  and NH 4 Cl as the solute. Another example is Napthalene (used in mothballs) can be  dissolved in benzene. In this example benzene is the solvent and napthalene is the  solute. Solutes dissolved in water (solvent) are called aqueous solutions. Not all substances are  soluble in water. Why do some substances dissolve in water and others don't? It has to do  with the structure of the water molecule. Oxygen has a greater attraction for electrons, so the shared electrons (bonding electrons)  spend more time close to oxygen then to either of the hydrogens. This gives oxygen a
