Why does 0.1M acetic acid conduct electricity better than 6M acetic acid?

0.1M acetic acid conducts electricity better than 6M acetic acid because acetic acid is a weak electrolyte that partially dissociates into ions in solution. At lower concentrations, such as 0.1M, the degree of dissociation is higher relative to the concentration of acetic acid, resulting in a greater number of free ions available to conduct electricity. In contrast, at higher concentrations like 6M, the increased presence of undissociated acetic acid molecules leads to a lower relative concentration of ions, reducing the overall conductivity of the solution.
