Verified step by step guidance1
Understand the definition of an Arrhenius acid: An Arrhenius acid is a substance that increases the concentration of hydrogen ions (H⁺) in aqueous solution.
Identify the chemical formula of each option: Cl⁻, NO₂⁻, NH₃, H₂SO₄, and KOH.
Determine which of these substances can release H⁺ ions when dissolved in water. Consider the chemical structure and composition of each option.
Recognize that H₂SO₄, sulfuric acid, is a well-known Arrhenius acid because it dissociates in water to produce H⁺ ions.
Conclude that H₂SO₄ is the correct answer as it fits the definition of an Arrhenius acid by increasing the concentration of H⁺ ions in solution.
