Solution

• A homogeneous mixture of two or more substances
  in a single phase
• Particles are thoroughly mixed and remains mixed
  indefinitely
• Components of a solution
• Solvent does the dissolving the larger amount
• Solute is being dissolved the smaller amount

Solute-Solvent Combinations

• Solutes and solvents can be any state of matter.
• Look at page 402 for examples
• Alloys solid solutions of metals

Electrolytes Nonelectrolytes

• Electrolyte a substance that dissolves in water
  to give a solution that conducts electric current
  
• Ionic compounds and highly polar molecules form
  electrolytes
• Nonelectrolytes a substance that dissolves in
  water to give a solution that does not conduct
  electricity
