5Solution
- 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

p. 402
7Solute-Solvent Combinations
- Solutes and solvents can be any state of matter.
- Look at page 402 for examples
- Alloys solid solutions of metals

15Electrolytes 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
