The conductivity of a solution is how much electricity it can conduct. Under what circumstances can I solution conduct electricity?
When there are cations with extra electrons that can flow through the electrode
When there are cations and anions that can cause electrons to flow through the electrode
When cautions move towards the positive electrode and anions move towards the negative electrode
When there are anions that do not give up their extra electrons to the electrode
All of these circumstances can allow a solution to conduct electricity.
The correct answer is:
When there are cations and anions that can cause electrons to flow through the electrode
