Electrolytes vs. NON-Electyrolytes in Solutions p. 399
Electrolytes conduct ________________________.
All ______________compounds and strong ______________dissociate into their _____________in solutions
of water. These cations and anions are positive and negative therefore the act just like poles on a battery and
conduct electricity.
NON-polar compounds are NON-metals and NON-metals combined. They are called covalent molecular
compounds. Therefore they do not conduct ____________________.
