Homogeneous Aqueous Solutions Solutions  A.    Soluble 1.   Capable of being dissolved B.    Solution   1.   A homogeneous mixture of two or more substances in a single phase C.    Solvent 1.   The dissolving medium in a solution; major component in a solution   D.    Solute 1.   The dissolved substance in a solution   E.   Types of solutions 1.   Gaseous mixtures a.    Air is a solution  2.   Solid solutions  a.    Metal alloys (e.g. Brass is a solution of copper and zinc) 3.   Liquid solutions  a.    Liquid dissolved in a liquid (alcohol in water) b.   Solid dissolved in a liquid (salt water) Dissolving The kinetic molecular theory as applied to gases can be extended to explain how the solute and solvent  particles are in constant random motion. The kinetic energy of this motion causes diffusion of the solute into  the solvent, resulting in a homogeneous solution. When a solid is in contact with a liquid, at least some small  degree of dissolution always occurs. Solutes: Electrolytes vs. Nonelectrolytes A.    Electrolyte 1.   A substance that dissolves in water to give a solution that conducts electric current 2.   Solutions of acids, bases and salts are electrolytes B.    Nonelectrolyte
