The bulb glows in the presence of acids during the activity because acids promote the flow of electric current, completing the circuit and allowing the bulb to light up. Acids contain ions, such as hydrogen ions (H⁺), which can conduct electricity when dissolved in water. When the electrodes are immersed in an acidic solution, the ions facilitate the flow of electrons between them, creating an electric current. This current passes through the filament of the bulb, heating it and causing it to emit light. The ability of acids to conduct electricity is a fundamental property related to their ionization in aqueous solutions.
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,Read more
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.
The experiment suggests that hydrochloric acid (HCl) readily produces hydrogen ions (H⁺) in solution.

The experiment suggests that hydrochloric acid (HCl) readily produces hydrogen ions (H⁺) in solution. When the electrodes are immersed in the hydrochloric acid solution, the conductivity of the solution increases, allowing the flow of electric current. This indicates the presence of mobile ions, primarily H⁺ and Cl⁻, in the solution. The ability of hydrochloric acid to conduct electricity is attributed to its strong ionization in water, dissociating into H⁺ and Cl⁻ ions. The observed conductivity and the subsequent glow of the bulb imply the efficient production of hydrogen ions, contributing to the electrical conductivity of the solution.
An alkali specifically refers to a soluble base that dissolves in water, producing hydroxide ions (OH⁻). This distinguishes alkalis from other bases, which may or may not be soluble in water. Alkalis are typically metal hydroxides, such as sodium hydroxide (NaOH) and potassium hydroxide (KOH), knownRead more
An alkali specifically refers to a soluble base that dissolves in water, producing hydroxide ions (OH⁻). This distinguishes alkalis from other bases, which may or may not be soluble in water. Alkalis are typically metal hydroxides, such as sodium hydroxide (NaOH) and potassium hydroxide (KOH), known for their ability to increase the concentration of hydroxide ions in aqueous solutions. In contrast, other bases may not necessarily produce hydroxide ions when dissolved. The characteristic presence of hydroxide ions in solution, giving rise to alkaline properties, is the key feature that differentiates alkalis from other bases.
Cautionary advice regarding handling alkalis includes wearing protective gear such as gloves and goggles to prevent skin and eye contact. Alkalis, particularly strong ones like sodium hydroxide (NaOH), can cause severe burns and eye damage. Avoid inhaling alkali fumes, as they may be harmful to theRead more
Cautionary advice regarding handling alkalis includes wearing protective gear such as gloves and goggles to prevent skin and eye contact. Alkalis, particularly strong ones like sodium hydroxide (NaOH), can cause severe burns and eye damage. Avoid inhaling alkali fumes, as they may be harmful to the respiratory system. When diluting alkalis, add the substance to water slowly to control heat release, as the dissolution of strong alkalis is exothermic. Promptly neutralize and wash off any spilled alkali with copious amounts of water. Adequate ventilation is essential when working with alkalis to minimize exposure to vapors.
