Electrolytes
A substance that
ionizes
when placed in a suitable solvent
Include most ionic compounds (salts), acids & bases

they can actually conduct electricity!

Polarity & Solubility
Polarity
- separation of electric charge
Occurs from the distribution of charge in a molecule and/or the shape of the molecule
Electronegativity
– the “pull” for electronsSlide6
Water is the “universal solvent”
because of its polaritySlide7
Polar examples: Most ionic substances such as salts, acids, bases
Nonpolar examples: noble gases,
diatomics
, methaneSlide8
Basic Rules for Solubility
Polar dissolves polar
Nonpolar dissolves nonpolar
Polar CANNOT dissolve nonpolar (or the other way around)
