प्रश्न
Give appropriate scientific reasons for The electrical conductivity of acetic acid is less in comparison to the electrical conductivity of dilute sulphuric acid at a given concentration.

उत्तर
Sulphuric acid is a strong acid compared to acetic acid. A strong acid has more ions than a weak one, and so, its solution will be a better electrical conductor than a weak acid. So, the electrical conductivity of acetic acid is less in comparison of electric conductivity of sulphuric acid.
