Question

Which of the following solutions will not conduct electricity?

[1 mark]

• A. Dilute hydrochloric acid
• B. Dilute acetic acid
• C. Glucose solution
• D. Dilute ammonium hydroxide

Answer 1

The correct option is C Glucose solution

Conduction of electricity occurs due to the movement of ions. Dilute hydrochloric acid (HCl), dilute acetic acid $\left(C{H}_{3}COOH\right)$, and dilute ammonium hydroxide $\left(N{H}_{4}OH\right)$ conduct electricity because they dissociate into ions in respective solutions.

Glucose molecules, on the other hand, do not dissociate into ions in the aqueous solution. So, glucose solution does not conduct electricity.
