12 Questions
What is the main difference between strong and weak electrolytes?
Strong electrolytes completely dissociate in solution, weak electrolytes have less than 100% dissociation
How do metallic conductors and electrolytic conductors differ in conducting current?
Metallic conductors conduct current through the flow of electrons; electrolytic conductors do so through the flow of ions
In which conditions does the conductivity of metallic conductors decrease?
With increasing temperature due to increasing electron scattering
What is the role of the nature of the electrolyte and solvent on the conductivity of electrolytic conductors?
They affect the conductivity of electrolytic conductors
What is converted into electrical energy in electrochemical cells?
Chemical energy
What does electrode potential refer to?
The ability of an electrode to gain or lose electrons
Which type of conductors conduct current due to the flow of ions?
Electrolytic conductors
What happens to the conductivity of metallic conductors with increasing temperature?
Decreases
How do strong electrolytes differ from weak electrolytes in a solution?
Strong electrolytes completely dissociate in solution
What is the main role of electrochemical cells?
Convert chemical energy into electrical energy
Why do shortcuts like 'loan' and 'panic' help in remembering processes in electrochemical and electrolytic cells?
They are mnemonic devices for process steps
In non-standard conditions, what is electrode potential a measure of?
Ability of an electrode to gain or lose electrons
