How does dissociation affect conductivity?
Ionic compounds, such as sodium chloride, dissociate completely into sodium and chloride ions. Since ions carry charge in aqueous solutions ( sodium is positively charged and chlorine is negatively charged) they are able to conduct electricity.
Strong acids and strong bases dissociates completely and are therefore strong electrolytes.
Hydrochloric acid is a strong acid and dissociates completely to form hydrogen and chloride ions.
Sodium hydroxide, a strong base, dissociates completely to form sodium ions and hydroxide ions.
A weak acid, such as acetic acid (
The most common species is the undissociated acid.
Since most of the acid does not break apart or dissociate, this is a weak electrolyte and therefore hardly conducts electricity.
