Flashcards
Strong Electrolyte
Strong Electrolyte
A solution that conducts electricity strongly due to a high concentration of ions.
Weak Electrolyte
Weak Electrolyte
A solution that conducts electricity weakly because it only partially ionizes in solution.
Non-Electrolyte
Non-Electrolyte
A substance that does not ionize in solution and thus does not conduct electricity.
Ionization
Ionization
The process by which a neutral atom or molecule acquires a positive or negative charge.
