QQuestion
Which of the following has the highest electrical conductivity?
(a) Aqueous solution of sugar
(b) Pure water
(c) Liquid hydrogen chloride
(d) None of these
✓Answer
(d) None of these
Explanation
- Aqueous sugar solution: Sugar is a covalent compound that dissolves as neutral molecules, not ions.
- Pure water: Contains almost no free ions (extremely weak self-ionization).
- Liquid HCl: Pure covalent liquid without free ions (it only ionizes and conducts when dissolved in water).
