Question

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> A bulb is observed to glow when lemon juice is used as an electrolyte in a circuit. Why does it seem to glow dimmer, when honey is added to it?

• A. Addition of honey increases conductivity
• B. Charges in lemon juice get absorbed by honey
• C. Addition of honey decreases conductivity
• D. Charges in honey get absorbed by lemon juice

Answer 1

The correct option is C Addition of honey decreases conductivity

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Lemonade has citric acid in it. This dissociates into ions which facilitate the conduction of electricity.
On the other hand, honey doesn't have any ions in it. Thus, when honey is added to the lemonade, the conductivity of the solution decreases, which is why, the bulb glows dimmer.
