Answer 2

Dissociation of Sodium Carbonate in Water

When sodium carbonate (Na2CO3) dissolves in water, it dissociates into its constituent ions, sodium (Na+) and carbonate (CO3^2-) ions. This dissociation is irreversible, meaning that once the compound dissolves, it remains in its dissociated form in the water solution. Sodium carbonate is a strong electrolyte, meaning it dissociates almost completely in water, producing a high concentration of ions. Therefore, it is considered a strong electrolyte in aqueous solution [[1]].

Dissociation of Hydrogen Sulfide in Water

Hydrogen sulfide (H2S) is a weak acid that partially dissociates in water. When hydrogen sulfide dissolves in water, it forms hydrosulfide ions (HS-) and hydrogen ions (H+). The dissociation of hydrogen sulfide is reversible, meaning that the reaction can go in both directions. However, in water, the forward reaction is favored, resulting in the formation of some hydrosulfide ions and hydrogen ions. Therefore, hydrogen sulfide is a weak electrolyte in aqueous solution [[2]].

Dissociation of Ammonia in Water

Ammonia (NH3) is a weak base that partially dissociates in water. When ammonia dissolves in water, it reacts with water molecules to form ammonium ions (NH4+) and hydroxide ions (OH-). The dissociation of ammonia is reversible, but in water, the forward reaction is favored, resulting in the formation of some ammonium ions and hydroxide ions. Therefore, ammonia is a weak electrolyte in aqueous solution [[3]].

Strongest Electrolyte in Aqueous Solution

Among the options provided, hydrochloric acid (HCl) is the strongest electrolyte in aqueous solution. When hydrochloric acid dissolves in water, it completely dissociates into hydrogen ions (H+) and chloride ions (Cl-). This complete dissociation makes hydrochloric acid a strong electrolyte, as it produces a high concentration of ions in the solution [[4]].
