CBSE Class 8 Answered

For the given question, they have which of the following solutions does not conduct electricity?

• Vinegar solution: Vinegar will conduct electricity since it dissociates into ions when dissolved in water.
• Sugar Solution: Sugar dissolves in water as a covalent molecule and does not dissociate into ions. Therefore, it does not conduct electricity.
• lemon juice solution: Lemon juice contains citric acid, which dissociates into ions in solution, making it a good conductor of electricity.
• Caustic soda solution: Caustic soda, or sodium hydroxide (NaOH), is an electrolyte that dissociates into ions in solution, thus conducting electricity.

Hence the only correct answer is option B which is the sugar solution.
