Which of the following is true about the concentration of H⁺ ions in an acid according to the Arrhenius theory?
Which of the following is true about the concentration of H⁺ ions in an acid according to the Arrhenius theory?
- The concentration of H⁺ ions determines the color of an acid.
- The higher the concentration of H⁺ ions, the stronger the acid. (correct)
- The concentration of H⁺ ions does not determine the strength of an acid.
- The lower the concentration of H⁺ ions, the stronger the acid.

Study Notes
Arrhenius Theory of Acids and Bases
- An acid is a substance that dissociates in water to produce hydrogen ions (H⁺).
- A base is a substance that dissociates in water to produce hydroxide ions (OH⁻).
Concentration of Ions
- The concentration of H⁺ ions in an acid is directly related to the strength of the acid.
- The concentration of OH⁻ ions in a base is directly related to the strength of the base.
Acid-Base Reactions
- When an acid reacts with a base, it produces a salt and water according to the Arrhenius theory.
- The reaction involves the neutralization of H⁺ ions from the acid and OH⁻ ions from the base, resulting in the formation of water.
