Which of the following does not conduct electricity?
Open in App
Solution
The correct option is C
Lemon juice conducts electricity as it contains an acid i.e citric acid. So, when this acid is dissolved in water, it releases hydrogen ions and hence conducts electricity.
Caustic soda is sodium hydroxide, it conducts electricity as it is a base. So, when this base is dissolved in water, it releases hydroxide ions. Due to the presence of ions, it conducts electricity.
Sugar solution does not conduct electricity as it will not produce ions which are responsible for carrying current.
Vinegar solution conducts electricity as it contains an acid i.e acetic acid. So, when this acid is dissolved in water, it releases hydrogen ions and hence conducts electricity.
