Voiceover
Hydrochloric acid, a strong electrolyte, is almost completely ionized in solution as shown by its high conductivity. Acetic acid is a weak electrolyte and a solution of the same concentration displays low conductivity.

Discussion
The difference between strong and weak electrolytes is shown by comparing the conductance of 0.1M HCl and 0.1M acetic acid. Although the molar concentrations are the same, HCl, a strong electrolyte, is almost completely ionized. Acetic acid, a weak electrolyte is only partially ionized.
