True or False: Ions are charged particles.

• true

• false

What is an electrolyte?

• a substance that conducts electricity

• a substance that does NOT conduct electricity

• a substance that ONLY strongly conducts electricity

• a substance that ONLY weakly conducts electricity

What makes an electrolyte strong?

• the ions dissociate completely

• the ions dissociate partially

• the ions dissociate into smaller molecules

• the ions do NOT dissociate

What makes an electrolyte weak?

• the ions dissociate completely

• the ions dissociate into smaller molecules

• the ions dissociate partially

• the ions do NOT dissociate

Select the true statement about non-electrolytes?

• the ions do NOT dissociate

• the ions dissociate completely

• the ions dissociate partially

• the molecule dissociates into smaller molecules
