Question

Explain why an aqueous solution of glucose does not conduct electricity.

Answer 1

Conductance: The conductance of a solution depends upon the free ions present in the solution. The higher the number of ions in a solution, higher will be conductivity of the solution.

Glucose solution:

• Glucose is a covalent compound that is formed by the sharing of electrons between the constituent atoms of glucose.
• Since glucose is a covalent compound. So, the aqueous solution of Glucose does not dissociate into its constituent ions.
• So in the case of Glucose, no free ions are there to conduct electrical charges across the solution.
• Therefore, the Glucose solution is a non-electrolyte and is a bad conductor of electricity.

Hence, the Glucose solution does not conduct electricity.
