Question
Which of the following liquids is a good conductor of electricity?
- Sugar solution
- Alcohol
- Distilled water
- Seawater
Hint:
Seawater is a good conductor of electricity as it has positive and negatively charged ions.
The correct answer is: Seawater
- The solutions that have positive and negative ions act as good conductors.
- Electrolytes are used to conduct electric current as they have charged ions.
- The seawater contains sodium and chloride ions that possess positive and negative charges and is a good conductor.
