1. Solutions A Homogeneous Mixture
Questions to Consider:
What is a solution?
What are the parts to a solution?
What are the characteristics of a solution?
What is an electrolyte?

2. Solutions Homogeneous mixture of substances in the same physical state
Atoms, molecules, ions are evenly distributed throughout the mixture
Can be separated by:
Distillation (boiling point)
NOT filtration
Solvent
Solute

3. Types of Solutions – Solid
Solid Solutions
Alloy – solid metal atoms are even mixed
Brass (Cu + Zn)
Bronze (Cu + Sn or Al)
Steel (Fe + C)
White Gold (Au + Ni)
Pewter (Sn + Pb)

4. Types of Solutions – Gas
Gas Solutions
Any mixture of gases becomes a gas solution because gases will always spread out evenly
Largest Gaseous Solution – Air!

5. Types of Solutions - Liquid
Liquid Solutions
Liquid dissolved in a liquid
Solid dissolved in a liquid
Aqueous – dissolved in water
Examples:
Contact Solution
Salt Water
Lemonade

6. Parts of a Solution Solute – Solvent – Universal Solvent – is H2O!!
substance being dissolved;
present in smaller amounts
Solvent –
substance doing the dissolving;
present in larger amounts (the liquid)
Universal Solvent – is H2O!!
Solute
Solvent

7. Characteristics of a Solution
Homogeneous mixture of 2 or more substances
Cannot be filtered; will not separate
Can be distilled
Clear – you can see through it
Uniform color
SOME solutions can conduct electricity (ELECTROLYTES)

8. What is an electrolyte?
An electrolyte is an ion that has formed by dissolving an ionic substance in water
Electrolytic solutions can conduct electricity (because ions act as electron carriers and complete a circuit)
