1. Parts of a Solution
A. SOLUTE
– Part being
dissolving
– Ex: sugar, salt
B. SOLVENT
– Part doing the
dissolving
– Water is the
universal solvent
– Ex: water, alcohol
2. Solubility
• Ability of a solute
to dissolve in a
solvent
• Determined by
attraction between
solute and solvent
3. Factors Affecting Solubility
A. Polarity
– Substances are polar
(have north & south) or
nonpolar
– Likes will dissolve
likes
B. Temperature
– Increase solvent
temperature increase
solubility
4. 3 Level of Solution
1. Saturated
– Contains as much solute as
the solvent at a given
temperature
2. Unsaturated
– Holding little solute in
much solvent
3. Supersaturated
– Containing more solute
than it normally hold at a
given temperature
5. Electricity & Solutions
• Electrolyte
– Solution that can
conduct electricity
– Ex: Salt and Water
• Nonelectrolyte
– Solution that cannot
conduct electricity
– Ex: Sugar and Water
