Question
Which of the following solutions cannot conduct electricity?
- Sugar in water
- NaCl in water
- MgCl2 in water
- KCl in water
Hint:
To conduct electricity, any elements or solutions should have positive and negative ions.
The correct answer is: Sugar in water
The solution of sugar and water can't conduct the electricity.
- Any elements or solutions that have positive and negative ions can conduct electricity.
- NaCl, KCl, and MgCl2 all possess positive and negative ions like Na+, K+, and Cl- that can conduct electricity.
- The solution of sugar and water cannot dissociate and thus, can't conduct electricity.
