Glucose and alcohol solutions do not conduct electricity, indicating that they do not facilitate the flow of electric current and thus are not acidic.
What is observed regarding the conductivity of glucose and alcohol solutions during the activity?

During the activity, solutions of glucose and alcohol typically do not conduct electricity effectively. Glucose and alcohols, like ethanol, are covalent compounds that do not readily dissociate into ions in solution. Since electrical conductivity in a solution is mainly due to the presence of ions, the lack of significant ionization in glucose and alcohol solutions results in poor electrical conductivity. Unlike acids or ionic compounds, these non-ionic substances do not provide a pathway for the flow of electric current. Therefore, the bulb in the conductivity experiment would likely not glow when electrodes are immersed in solutions of glucose or alcohol.
