Which statement is true regarding strong Arrhenius acids?

Strong Arrhenius acids are defined as substances that completely dissociate into their ions when dissolved in water. This means that they readily produce protons (H⁺ ions) and fully ionize in solution. For example, hydrochloric acid (HCl) dissociates entirely into H⁺ and Cl⁻ ions. This complete dissociation is what provides the characteristic acidic properties of such solutions, such as a low pH and the ability to conduct electricity due to the presence of free-moving ions.

In contrast, other statements do not accurately describe the behavior of strong Arrhenius acids. Partial dissociation would indicate a weak acid rather than a strong acid, and being intact in molecular form contradicts the very definition of a strong Arrhenius acid, which emphasizes full dissociation. Additionally, strong acids are indeed capable of conducting electricity in solution due to the abundant free ions. Hence, the assertion that strong Arrhenius acids fully dissociate and produce protons in solution is what makes this statement true.
