Question

What would happen if the electrodes were put in a saturated solution of glucose which is dissolved in water?

• A. Light bulb would glow
• B. Light bulb would remain dark
• C. Apparatus would combust
• D. Glucose molecules would dissociate
• E. None of the above

Answer 1

The correct option is B Light bulb would remain dark

If the electrodes were put in a saturated solution of glucose which is dissolved in water, light bulb would remain dark.
This indicates that no electricity is passing through aqueous glucose solution.
Glucose is a non electrolyte. Hence, in aqueous solution of glucose, no ions are present. Hence, it cannot conduct electricity.
